Abstract:
|
Many collegiate team sports in the United States are organized with multiple leagues where teams play a fairly full schedule of games against league opponents with a sparser schedule of games between teams from different leagues. This often creates difficulties when teams are to be compared across all leagues for national rankings or seeding in post season tournaments. A number of methods have been proposed to calibrate teams while accounting for performance and the quality of opponents. We use Monte Carlo simulations of multiple seasons to compare several existing models, such as raw winning percentage, rating percentage index (RPI), Bradley-Terry (KRACH) and Poisson scoring rates (CHODR), for rating college ice hockey teams.
