Quetelet Seminar: An introduction to plus-minus ratings for football players by dr. Lars Magnus Hvattum (Molde University College)


Evaluating individual players in team sports is challenging, and perhaps in particular for fluid invasion sports such as association football. Recent advances in data collection, providing both event data and tracking data, may improve our ability to model and evaluate the performance of players, but such data is not yet publicly available. There is therefore a question about whether one can evaluate individual players given the data currently available. In basketball and ice hockey, variants of plus-minus ratings have been used with some success. These ratings are top-down ratings distributing credit for the performance of a team onto individual players through the use of regression models. This talk describes how such ratings can be calculated for players in association football, given the particular features of that game. The resulting ratings are evaluated from several perspectives, including their predictive ability and their connections to event based key performance indicators for players.
