A Model for Predicting the Outcomes of Basketball Games
نویسندگان
چکیده
We investigated the task of predicting the outcomes of sporting events, in particular, basketball games. In two experiments, college students predicted the outcomes of a series of National Basketball Association (NBA) games. Following each prediction, the subject received feedback in the form of the actual outcome of the NBA game. After a period of initial learning about the relative strengths of the teams, the subjects were surprisingly successful in their predictions. We examined expert-novice differences by comparing the published predictions of professional oddsmakers to the predictions of the experimental subjects. The average predictions by the subjects were approximately as accurate as the predictions of experts. Finally, we applied a mathematical model, developed originally as an account of simpler learning experiments, to the subjects’ responses. We found that the course of the subjects’ learning about the teams was well-described by this model.

This paper offers an extension to TrueSkill, a Bayesian method for ranking players and predicting outcomes of multiplayer games, for cases where a game is highdimensional. TrueSkill was originally developed by Microsoft Research to rank and match XBox Live players, but offers a general method for inferring player skill based almost exclusively on the win-loss outcome of a match. Although such a...

Abstract The effectiveness of different educational methods in learning different types of motor skills has been considered. However, comparisons of these methods in regulated team sports games have been less studied. Therefore, the aim of the present study was to compare the three educational methods of imagery, observation, and execution of in-field pattern on the performance of regulated ga...
