A Soccer-Factor-Model
To Decipher a Soccer-Player’s Inherent SkillOnline
Inspired by the asset-pricing literature, the Soccer-Factor-Model (SFM) is an attempt to determine a soccer player’s alpha
, i.e. his/her inherent skill. In this application, skill
is defined as a player’s probability to score a goal after accounting for factors that are actually to be attributed to his team’s out- or under-performance vis-à-vis the opponent.
In that way, the SFM answers the question, of whether a player’s observed goals are an over- or understatement of his true
skill.
