The Soccer Factor Model
-- A Model to Disentangle True Skill from Observed Performance --
I had been a passionate soccer player for about 20 years. I was obsessed with soccer. No matter whether it was Bundesliga, Serie A, Premier League, La Liga (the good old days of Laola1.tv), or the Australian A-League -- soccer was everything!
Ever since though, I have been wondering how much of a player's performance is due to his own skill and ability, and how much has actually to be attributed to his team's strength ?!
Based on Andorra and Göbel (2024) our dashboard features estimates of skill and scoring probabilities of select players in four major European leagues.
The dashboard is updated on a weekly basis throughout the football season.
Inspired by the literature on financial asset-pricing this model started out as just a little side project, and only after joining with Alexandre Andorra, did this model become...well...more skilled!
