Examples chosen by number of matches, not by deviation.
Undiano Mallenco × Real Madrid CF
## What the data says
Four results, each with its details and method.
Referee × club deviations after correction
**Verdict / q-value** With hundreds of comparisons, some look extreme by chance. The Benjamini-Hochberg correction accounts for this: a deviation is only called notable if q < 0.05. Otherwise: inconclusive. Inconclusive does not mean "no effect": with 11 matches, only a deviation of about ±1.57 points per match could have been detected.
0 notable out of 1,325 pairs
Before correction, 255 tests out of 6,535 fall below p < 0.05: the order of magnitude expected from chance alone.
[Summary of verdicts →](https://elcolegiado.com/studies/negreira-case/#verdicts)
The odds, a reliable benchmark
**Calibration** Across the whole Liga, actual points and points expected from the odds differ by only a few % per season: the odds are a reliable benchmark.
−1.3% to +1.8%
Deviation between actual points and points expected from the odds, whole Liga, in each of the 26 seasons.
[Calibration by season →](https://elcolegiado.com/studies/odds/)
Effect of VAR (2018-19)
**Effect of VAR** Whole-Liga average, four seasons before against four seasons after the arrival of VAR. VAR arrives the same season the payments end.
+26%
Penalties awarded per match, whole Liga: 0.290 → 0.364 (p = 0.001). VAR coincides with the end of the payments.

Negreira study: before / during / after
**Difference-in-differences** We measure the club's change between two periods, then subtract the change of a comparison group over the same periods. What remains is the change specific to the club.
−0.111 pt/match
Difference-in-differences of points − expected, Barça vs control group, 2001-18 → 2018-26: q = 0.27, inconclusive.

## How it works
Three steps, all documented.
[Methodology](https://elcolegiado.com/methodology/)
- 1 ### Open sources Scores, odds, referees, cards and penalties from 9,880 matches, gathered from public sources, normalised and cross-checked.
- 2 ### Expected points from the odds Before each match, the market gives the chances of a win, draw and defeat. Points obtained are compared with these expected points.
- 3 ### Corrected tests Every deviation is tested, then corrected for multiple comparisons: a deviation is only called notable if it survives the correction.
## Why trust us
- **Sources and licences** football-data.co.uk, Zenodo, Wikipedia: each file carries its licence. [Data](https://elcolegiado.com/data/#licences)
- **Neutrality** No ranking by deviation or by "suspicion", morally neutral colours, sample size always shown. [About](https://elcolegiado.com/about/)
- **Public corrections** Found an error? Report it: every correction is checked and recorded. [Corrections](https://elcolegiado.com/corrections/)

**Status of the proceedings as of 2 October 2026:** As of 1 September 2026 (EFE via Infobae; The Objective), the case is still at the investigation stage (instrucción) before Barcelona Investigating Court No. 1 (Juzgado de Instrucción n.º 1; Judge Alejandra Gil Lima): the judge refused a further extension requested by Real Madrid and supported by the Public Prosecutor's Office, but the investigation phase will not be closed before two witness statements scheduled for 13 November 2026, and an appeal concerning investigative measures remains pending before the Provincial Court (Audiencia Provincial).

## Context
Between 2001 and 2018, FC Barcelona paid money to companies linked to José María Enríquez Negreira, then vice-president of the referees' committee (CTA). The Spanish courts are investigating the case; no referee is being prosecuted.
Established facts, court decisions, allegations and ongoing proceedings are kept apart; each event links to its sources.
## Frequently asked questions
### Who is Negreira?
José María Enríquez Negreira is a former referee who was vice-president of the RFEF's Technical Committee of Referees (CTA) until 2018. Companies linked to him received payments from FC Barcelona. See the [sourced timeline](https://elcolegiado.com/studies/negreira-case/#chronologie).
### What is the Negreira case?
Between 2001 and 2018, FC Barcelona paid money to companies linked to José María Enríquez Negreira, then vice-president of the referees' committee (CTA). The Spanish courts are investigating the case; no referee is being prosecuted. The site compares those years with refereeing data, without presuming anything.
### What period do the payments cover?
From 2001 to 2018. The site compares three periods: before (2000-01), during (2001-02 → 2017-18) and after (2018-19 → 2025-26); see the [statistics by period](https://elcolegiado.com/studies/negreira-case/#statistiques).
### Is there a conviction or a trial date?
As of 2 October 2026, there has been no conviction and the case is still at the investigation stage: As of 1 September 2026 (EFE via Infobae; The Objective), the case is still at the investigation stage (instrucción) before Barcelona Investigating Court No. 1 (Juzgado de Instrucción n.º 1; Judge Alejandra Gil Lima): the judge refused a further extension requested by Real Madrid and supported by the Public Prosecutor's Office, but the investigation phase will not be closed before two witness statements scheduled for 13 November 2026, and an appeal concerning investigative measures remains pending before the Provincial Court (Audiencia Provincial). The dated details are under "Status of the proceedings".
### Has any referee been charged?
No. As of 2 October 2026, no referee is being prosecuted in this case; everyone mentioned is presumed innocent.
### Do the data show that referees favoured Barcelona?
No referee × club deviation remains notable after correction for multiple testing (1,325 pairs tested). These tests have limited power: with a median of 11 matches, only deviations of about ±1.57 points per match could be detected. Over the payment period, the only signals concern fouls and yellow cards (raw p 0.02 and 0.08); they do not survive the correction (q = 0.08 and 0.24). Compared with Real Madrid, the fouls and yellow-card balance moved notably after 2018 (q < 0.001 – 0.04): Barça's advantage shrank while Real Madrid's grew. This is not the case against the control group (q = 0.08 to 0.27). Playing style, VAR (2018-19) and the end of the payments coincide and cannot be separated. [See the verdicts](https://elcolegiado.com/studies/negreira-case/#verdicts)
### Where does the data come from?
Scores and odds from football-data.co.uk, referees and cards from Zenodo (BeSoccer) and Wikipedia, cross-checked; everything can be downloaded from the [Data](https://elcolegiado.com/data/) page and the method is published in the [methodology](https://elcolegiado.com/methodology/).
## Timeline
Status of the proceedings As of 2 October 2026
As of 1 September 2026 (EFE via Infobae; The Objective), the case is still at the investigation stage (instrucción) before Barcelona Investigating Court No. 1 (Juzgado de Instrucción n.º 1; Judge Alejandra Gil Lima): the judge refused a further extension requested by Real Madrid and supported by the Public Prosecutor's Office, but the investigation phase will not be closed before two witness statements scheduled for 13 November 2026, and an appeal concerning investigative measures remains pending before the Provincial Court (Audiencia Provincial). According to 2025-2026 sources, those still under investigation are FC Barcelona (as a legal entity), former presidents Rosell and Bartomeu, former executives, Negreira and his son; Joan Laporta was removed from the case in 2024 and Joan Gaspart has only been heard as a witness. The offence of bribery (cohecho) and the money-laundering line of investigation concerning the club were ruled out by the Audiencia in 2024, and a 2026 expert report found Negreira unfit to follow the proceedings, with no known court decision on the matter. No trial has been scheduled, no referee is being prosecuted, all persons named are entitled to the presumption of innocence, and the UEFA investigation opened in 2023 remains ongoing (receipt of a dossier from Real Madrid announced on 1 October 2026).

## Statistics: before / during / after
Periods: before = 2000-01 (a single season), during = 2001-02 → 2017-18 (payments), after = 2018-19 → 2025-26. The study preset compares Barça and Real Madrid with a control group (Atlético Madrid, Valencia CF, Sevilla FC). Every other club also has its figures on its page, and the [comparison tool](https://elcolegiado.com/compare/) lets you choose your own control group.
## Points obtained − expected points per match
Based on the average pre-match odds (margin removed). Select a group to see its three periods.
**Points − expected points** Before each match, the bookmakers' odds give the probability of a win, a draw and a defeat. Expected points = 3 × P(win) + P(draw). A positive deviation means the club took more points than the market predicted. Because the team's strength is already built into the odds, a big club has no "automatic" positive deviation.

Club-season block bootstrap; q = Benjamini-Hochberg correction over the 18 tests. Yellow cards and fouls also depend on playing style (possession, pressing), which the odds adjustment does not capture. VAR and the end of the payments coincide in 2018-19.
**Referee coverage: which seasons?**
- **Referee known** for at least 99% of matches in most seasons; less complete in 2006-07 (97.1%), 2008-09 (96.8%), 2010-11 (95.8%), 2011-12 (96.6%), 2012-13 (96.8%), 2013-14 (96.3%), 2024-25 (96.6%), 2025-26 (78.7%). "Teixeira Vitienes" matches not attributed to either brother count as unassigned.
- **Appointments** (referee × club frequency) and **important matches**: 2000-01 → 2024-25, seasons in which the referee is known for at least 90% of matches (2025-26 excluded).
- Measures **not involving the referee** (points vs odds, adjusted penalties, cards and fouls) cover all seasons for all clubs.
- VAR arrives in 2018-19, the same season the payments end.
## Referee × club: verdicts, appointments, important matches
## Summary of referee × club verdicts
All clubs, pairs with at least 5 matches (1,325 pairs)
**Verdict / q-value** With hundreds of comparisons, some look extreme by chance. The Benjamini-Hochberg correction accounts for this: a deviation is only called notable if q < 0.05. Otherwise: inconclusive. Inconclusive does not mean "no effect": with 11 matches, only a deviation of about ±1.57 points per match could have been detected.
| Measure | Tested | p < 0.05 | Favourable | Unfavourable | Inconclusive |
| --- | --- | --- | --- | --- | --- |
| Points − expected | 1,325 | 46 | 0 | 0 | 1,325 |
| Penalty balance | 1,325 | 38 | 0 | 0 | 1,325 |
| Red-card balance | 1,325 | 46 | 0 | 0 | 1,325 |
| Yellow-card balance | 1,325 | 62 | 0 | 0 | 1,325 |
| Foul balance | 1,235 | 63 | 0 | 0 | 1,325 |
Without correction, about 5% of tests fall below p < 0.05 by pure chance: that is the order of magnitude observed. After correction, no combination remains notable.
## Appointment frequency
A club's matches assigned to a referee, observed vs expected
**Appointments** Expected number = the referee's share of matches each season (among the matches they can take: never a club from their own region) × the club's matches.

**Important matches** Important match: opponent in the season's final top 4, or the Clásico (Barça – Real Madrid). The share of important matches refereed by this referee is compared with the share refereed by other referees for the same club. q = Benjamini-Hochberg correction across all combinations.

Important match: opponent in the season's final top 4 (recomputed standings: points, head-to-head, goal difference, goals scored), plus the Clásico for Barça and Real Madrid. Fisher's exact test per club × referee combination (at least 5 matches), Benjamini-Hochberg correction across all combinations, all clubs. Each referee's details are on their page.
### Why so many "inconclusive" results?
A referee × club pair has a median of 11 matches (244 pairs out of 1,325 have at least 20). Over so few matches, chance weighs heavily: the standard deviation of a club's points is about 1.18 points per match.
Detectable deviation (points per match, 80% power)
| Matches | Without correction | After correction |
| --- | --- | --- |
| 10 | ±1.05 | ±1.65 |
| 25 | ±0.66 | ±1.04 |
| 50 | ±0.47 | ±0.74 |
| 100 | ±0.33 | ±0.52 |
Share of tests with p < 0.05 before correction (chance alone gives about 5%)
| Measure | p < 0.05 |
| --- | --- |
| Points − expected | 3.5% |
| Penalty balance | 2.9% |
| Red-card balance | 3.5% |
| Yellow-card balance | 4.7% |
| Foul balance | 5.1% |
So "inconclusive" does not mean "no effect": only large deviations could be detected pair by pair. The period-level analyses (before / during / after) pool hundreds of matches and are far more sensitive. [Details in the methodology →](https://elcolegiado.com/methodology/#puissance)
## Limitations
**Limitations** What these figures cannot tell us.
- The odds reflect what the market knew before the match: a bias known to and priced in by the bookmakers would be underestimated.
- Cards and fouls depend on playing style, which the odds adjustment does not capture.
- The end of the payments and the arrival of VAR coincide (2018-19); matches behind closed doors in 2019-20 and 2020-21.
- These tests deal with aggregate results. They say nothing about any specific decision in a match.

## Definitions
**Expected points**
Before each match, the bookmakers' odds give the probability of a win, a draw and a defeat. Expected points = 3 × P(win) + P(draw). A positive deviation means the club took more points than the market predicted. Because the team's strength is already built into the odds, a big club has no "automatic" positive deviation.
**q-value**
With hundreds of comparisons, some look extreme by chance. The Benjamini-Hochberg correction accounts for this: a deviation is only called notable if q < 0.05. Otherwise: inconclusive. Inconclusive does not mean "no effect": with 11 matches, only a deviation of about ±1.57 points per match could have been detected.
**Difference-in-differences**
We measure the club's change between two periods, then subtract the change of a comparison group over the same periods. What remains is the change specific to the club.
**Strength-adjusted measures**
Each match is compared with Liga matches from the same season, at the same venue type (home/away) and between teams of comparable strength according to the odds. A positive value is favourable to the club.

- Across the whole Liga, the deviation between actual and expected points ranges from **−1.3%** to **+1.8%** depending on the season (2000-01 → 2025-26). [See](https://elcolegiado.com/studies/odds/#calibrage)
- **26** seasons out of 26 stay within 2% of expected points. [See](https://elcolegiado.com/studies/odds/#calibrage)
- 2 matches without odds are excluded from odds-based measures. [See](https://elcolegiado.com/studies/odds/#methode)
- An Elo model was tested for the archives and rejected: its expected points differ too much from those derived from the odds. [See](https://elcolegiado.com/studies/odds/#elo)
**In short:** The whole "points − expected" measure rests on the odds. Across the Liga, actual points deviate from expected points by −1.3% to +1.8% depending on the season.

Deviation
The 2019-20 and 2020-21 seasons (matches behind closed doors) are slightly below expectations. Probabilities = average market odds, bookmaker margin removed.
## By club, all seasons 2000-01 → 2025-26
Actual against expected points; sorted by number of matches, not by deviation
**Points − expected points** Before each match, the bookmakers' odds give the probability of a win, a draw and a defeat. Expected points = 3 × P(win) + P(draw). A positive deviation means the club took more points than the market predicted. Because the team's strength is already built into the odds, a big club has no "automatic" positive deviation.

## Method
**Method** How the odds become expected points.
- Source: football-data.co.uk, pre-match market average (not closing odds).
- Margin removed by proportional normalisation: p = (1/odds) / Σ(1/odds).
- Expected points = 3 × P(win) + P(draw), match by match.
[Details in the methodology →](https://elcolegiado.com/methodology/#cotes)
## A rejected trial: the Elo model
**A rejected trial: the Elo model** Why the archives have no expected points.
For the archives (1990-91 → 1999-00), which have no odds, an Elo model (expected points computed from past results only) was built and tested against the odds over 2000-01 → 2025-26. Its expected points differ by several points per club and season from those derived from the odds: it was rejected as a benchmark, and the archives remain descriptive.
## Limitations
**Limitations** What these figures cannot tell us.
- Proportional normalisation may leave a slight favourite-longshot bias.
- The odds include what the market knew before the match; a bias the market knew about would already be "in the odds".
- 2 matches without odds are excluded from odds-based measures.
## Definitions
**Expected points**
Before each match, the bookmakers' odds give the probability of a win, a draw and a defeat. Expected points = 3 × P(win) + P(draw). A positive deviation means the club took more points than the market predicted. Because the team's strength is already built into the odds, a big club has no "automatic" positive deviation.
**q-value**
With hundreds of comparisons, some look extreme by chance. The Benjamini-Hochberg correction accounts for this: a deviation is only called notable if q < 0.05. Otherwise: inconclusive. Inconclusive does not mean "no effect": with 11 matches, only a deviation of about ±1.57 points per match could have been detected.
**Difference-in-differences**
We measure the club's change between two periods, then subtract the change of a comparison group over the same periods. What remains is the change specific to the club.
**Strength-adjusted measures**
Each match is compared with Liga matches from the same season, at the same venue type (home/away) and between teams of comparable strength according to the odds. A positive value is favourable to the club.

Analysis
# Methodology
How every figure on the site is produced, and what it cannot tell us.
- 2000-01 → 2025-26
- 9,880 matches
- Updated on 3 October 2026
**Coverage:** Liga only (Primera División). Copa del Rey and Champions League: coming later.
## Sources

- **Referee retained**: up to three sources (Zenodo/BeSoccer, Zenodo 7831873, Wikipedia) vote; the majority wins, and a disagreement without a majority leaves the referee blank (conflict log on the Data page).
Sources set aside: sites whose terms of use forbid collection, or that are protected against bots (no protection was circumvented).
## Standardisation
**Teams**: an alias table links every spelling to a single identifier; an unknown name makes the build fail.
**Referees**: identifier = the two surnames without accents. The spelling variants encountered are listed on each profile. 80 referees are identified.
**The Teixeira Vitienes brothers**: Fernando Teixeira Vitienes and José Antonio Teixeira Vitienes both refereed in Primera. The main source conflates them from 2010-11; when no other source gives the first name, the match is filed under a separate, [undistinguished](https://elcolegiado.com/referees/teixeira-vitienes-ambigu/) entry (44 matches), excluded from the referee × club tests.
**Penalties awarded** = penalties scored + penalties missed by the team. **Odds**: market average, otherwise the average of the available bookmakers.
## Periods
- **Before**: 2000-01. According to the public prosecutor the payments began "at least in 2001": this single season serves as a sensitivity check.
- **During**: 2001-02 → 2017-18, the period of the payments.
- **After**: 2018-19 → 2025-26. Coincides with the arrival of VAR (2018-19): the two effects cannot be separated.
## Odds: which figure, which correction
- **Source**: football-data.co.uk, **pre-match market average** (columns `BbAv*` from 2005 to 2019, `Avg*` from 2019 to 2026; before 2005, or when no average is available, the average of the available bookmakers). These are **not** closing odds.
- **Margin removed by proportional normalisation**: p = (1/odds) / Σ(1/odds) over the three outcomes. Shin's method is not used; proportional normalisation may leave a slight favourite–longshot bias (see limitations).
- **2 matches out of 9,880 without odds**: excluded from the "points − expected" measures and from the strength adjustments, kept everywhere else.
## Expected points
For each match, the probabilities of a win, draw and defeat derived from the odds give the expected points.
Expected points = 3 × P(win) + P(draw)
The deviation points won − expected points neutralises the team's strength: a big club has many expected points, so it has no "automatic" positive deviation. Across the whole Liga, this deviation ranges from −1.3% to +1.8% depending on the season: the odds are a reliable benchmark (see [the study](https://elcolegiado.com/studies/odds/)).
## Exact distribution of points
The site's signature chart computes, in your browser, the exact probability of every points total over a series of matches if only the odds mattered. It starts from a "0 points with certainty" distribution, then, match after match, combines it with the three possible outcomes: 0 points (defeat), 1 point (draw), 3 points (win), each with its probability. No random draws: the result is exact.
The **two-sided p-value of a discrete distribution** is defined the same way everywhere:
p = 2 × min( P(X ≤ observed), P(X ≥ observed) ), capped at 1
In the analysis (Python), the probabilities come from a simulation, with the usual "+1" correction ((k + 1) / (n + 1)); on the site they are computed exactly. The smaller p is, the rarer the actual total is in light of the odds. In the Explorer and the comparison tool, p is **not** corrected for multiple comparisons: it is expressed as "common" (p ≥ 0.10), "uncommon" (0.01 ≤ p < 0.10) or "rare" (p < 0.01).
## Referee × club tests
Every referee × club pair with at least 5 matches is tested on five measures (1,325 pairs, all clubs):
- **Points − expected**: the series of matches is replayed thousands of times, drawing each result according to the odds; the p-value is how often chance alone produces a deviation at least as large.
- **Balances of penalties, red cards, yellow cards and fouls** (stratified permutation): the pair's matches are compared with the same club's other matches in the same season under other referees, by randomly reallocating matches between referees.
Below 15 matches, the pair is flagged "small sample". Below 5 matches, it is not tested: "descriptive" chip. A dedicated page exists from 3 matches.
## Benjamini-Hochberg correction
With hundreds of comparisons, about 5% give p < 0.05 by pure chance. The Benjamini-Hochberg correction ranks the p-values and adjusts them to the number of tests, giving a **q-value**. A deviation is only called notable ("favourable to the club" or "unfavourable to the club") if q < 0.05; this keeps the expected share of false alarms below 5%. Otherwise: "inconclusive".
The **families** of tests corrected together:
- **Referee × club**: one family **per measure** (points, penalties, red cards, yellow cards, fouls), each over all pairs from all clubs with at least 5 matches (1,325 pairs; slightly fewer for fouls, unavailable before 2005-06).
- **Appointments**: one family (2,094 pairs).
- **Important matches**: one family (1,297 combinations).
- **The study's differences-in-differences**: one family (18 tests).
The count of "notable results" adds up the q < 0.05 across all referee × club families.
## Why so many "inconclusive" results?
### Why so many "inconclusive" results?
A referee × club pair has a median of 11 matches (244 pairs out of 1,325 have at least 20). Over so few matches, chance weighs heavily: the standard deviation of a club's points is about 1.18 points per match.
Detectable deviation (points per match, 80% power)
| Matches | Without correction | After correction |
| --- | --- | --- |
| 10 | ±1.05 | ±1.65 |
| 25 | ±0.66 | ±1.04 |
| 50 | ±0.47 | ±0.74 |
| 100 | ±0.33 | ±0.52 |
Share of tests with p < 0.05 before correction (chance alone gives about 5%)
| Measure | p < 0.05 |
| --- | --- |
| Points − expected | 3.5% |
| Penalty balance | 2.9% |
| Red-card balance | 3.5% |
| Yellow-card balance | 4.7% |
| Foul balance | 5.1% |
So "inconclusive" does not mean "no effect": only large deviations could be detected pair by pair. The period-level analyses (before / during / after) pool hundreds of matches and are far more sensitive.
## Strength adjustment
A dominant club wins more penalties and receives fewer cards because it dominates, not necessarily because of the referee. Each match is therefore compared with the Liga average for matches of the same strength according to the odds (deciles), in the same season and at the same venue (home or away). A positive value is favourable to the club.
## Difference-in-differences
We measure how a club changes between two periods, then subtract the change of a comparison group over the same periods: (A₁ − A₂) − (B₁ − B₂). The 95% confidence interval comes from a club-season block bootstrap (whole club seasons are resampled, to respect the dependence between matches of the same season). In the study, q = Benjamini-Hochberg correction over the 18 tests. The [comparison tool](https://elcolegiado.com/compare/) repeats this calculation in the browser for any club and any control group, with 2,000 draws and a fixed seed.
## Appointment frequency
Expected number of matches of a referee with a club = his share of Liga matches each season (among the matches he may officiate: never a club from his own region) × the club's matches. Poisson test, Benjamini-Hochberg correction.
## Important matches
A match is "important" for a club if the opponent finished in the season's **final top 4** (recalculated standings: points, head-to-head, goal difference, goals scored), plus the **Clásico** for Barça and Real Madrid. Period: 2000-01 → 2025-26 (referees known for all matches). For each club and each referee (at least 5 matches), the share of important matches he officiated is compared with that of the other referees: Fisher's exact test, then Benjamini-Hochberg correction.
## Archives 1990-91 → 1999-00
**Sources**: results and final standings from es.wikipedia season pages (complete); referee, date, penalties and cards from the clubs' season pages on en.wikipedia, when they provide them (CC BY-SA 4.0).
**Coverage**: referee known for 1,112 matches out of 3,964; this coverage is partial and depends on the clubs and on Wikipedia contributors, hence **not random**. Two points for a win until the season before 1995-96.
**Referee names**: cautious consolidation of spelling variants: when in doubt, two spellings are kept apart rather than wrongly merged; a few duplicates may therefore remain.
**Why no analysis**: no bookmaker odds exist for these seasons, so there are no expected points, and the refereeing data are incomplete and not random. An **Elo** model (expected points computed from past results only) was built and tested against the odds over 2000-01 → 2025-26; its expected points differ by several points per club and per season from those derived from the odds, so it was rejected as a benchmark (see `scripts/09_elo.py`). The archive pages are therefore purely descriptive: no tests, no verdicts.
## Limitations
- Odds reflect what the market knew: if a bias were known to bookmakers and priced in, the deviation from the odds would underestimate it.
- Pre-match market average rather than closing odds, margin removed proportionally (no Shin method): a slight favourite–longshot bias is possible.
- Liga only: the Copa del Rey and European competitions are not covered.
- Cards and fouls depend on playing style (possession, pressing), which the odds-based adjustment does not capture.
- The end of the payments and VAR coincide (2018-19); matches behind closed doors in 2019-20 and 2020-21.
- Yellow cards: the two sources agree on 85 to 88% of matches; a single-source series serves as a check.
- The final standings shown are recalculated from the matches (points, head-to-head, goal difference, goals scored); the official title prevails.
- These tests concern aggregate results. They say nothing about any specific decision in a match, and a statistical deviation is not proof.

# About · El Colegiado
> El Colegiado: an independent, neutral and non-commercial data platform on refereeing in the Liga.
Source: https://elcolegiado.com/about/
# About
Who makes El Colegiado, and on what principles.
**El Colegiado is a non-commercial project: no advertising, no paid offer, no commercial ties.**
## Independence
El Colegiado has no link with any club, federation, refereeing body, bookmaker or media outlet.
## Approach
We gather public sources (9,880 Liga matches, 2000-01 → 2025-26), standardise them, document every choice, and compare results with what the bookmakers' odds predicted. Everything is reproducible: the tables can be downloaded from the [Data](https://elcolegiado.com/data/) page and the method is described in detail in the [Methodology](https://elcolegiado.com/methodology/).
## Neutrality
- A fixed vocabulary: "deviation", "favourable to the club", "unfavourable to the club", "inconclusive".
- No ranking by deviation, verdict or "suspicion": lists are sorted by name, number of matches or date.
- Sample size always accompanies a deviation; small samples are flagged.
- Colours carry no moral meaning: lime and lavender for the two directions of a deviation, grey for "inconclusive".
- No photos of referees: the same neutral silhouette for everyone.
## Credits

## Usage guidelines
- A statistical deviation is not proof: never present it as evidence of biased refereeing.
- Quote the q-value (corrected for multiple comparisons) rather than the raw p-value, and always the sample size.
- "Inconclusive" does not mean "no effect": referee × club pairs often involve few matches.
- Keep the vocabulary neutral: "favourable to the club", "unfavourable to the club", "inconclusive".
- Respect the source licences, in particular the non-commercial use of the BeSoccer data.
