ABSTRACT
For all the complexities of individual matches, performance in soccer leagues, such as the English Premier League, is generally evaluated using a relatively simple process in which teams are awarded three points for a win, one point for a draw, and no points for losing. This means that there is an inherent mathematical structure to soccer leagues that can be utilised to predict the likely end-of-season (EoS) team position. Knowing where a team is likely to finish at the end of any season is a key issue for fans, players, and managers alike, since promotion and relegation depend on league position. In this chapter, using examples from the English Premier League, we show how R can be used to predict likely EoS league position. In particular, we show how the partial standings and Pythagorean expected points can be used to predict EoS league position. Performance indicators such as goal ratio, total shots ratio, and expected goals are also discussed.
