Referee Bias Analysis

Overview

A personal statistical analysis using the Crowdstorming dataset (Silberzahn et al., 2018) to examine whether referees issue red cards at different rates depending on players’ skin tone.

The main goal was to refresh R skills after working mainly in Python for the last few years.

Approach

Built three increasingly complex GLM/GLMM models, checking whether findings held up as complexity increased.

Tools

R, GLM/GLMM

Status

Write-up in progress. A next step is extending the analysis to yellow cards as an additional outcome variable.
