对NBA运动员能力的评价

On Estimating the Ability of NBA Players

Paul Fearnhead, Benjamin M. Taylor

摘要:

本文介绍了一种新的NBA球员能力评价模型和方法。其主要思想是通过比较他们的球队在场上和场下的表现来直接衡量一名球员的水平。这是通过控制比赛期间不同时间球场上其他球员能力的变化来实现的。新方法以结构化的方式使用多个赛季的数据来评估球员在一个单独赛季的能力,分别衡量防守和进攻的价值,并结合这些来给出一个整体评级。将考虑使用游戏统计数据来预测玩家的能力。使用2008/9赛季数据的结果表明,获得NBA MVP的勒布朗·詹姆斯是最佳球员。最佳防守球员是奥多姆,最佳新秀是威斯布鲁克,两人都没有在那个赛季获得NBA奖项。结果进一步表明,虽然经常报告的游戏统计提供了一些信息的进攻能力,他们没有表现出良好的预测防守能力。

英文摘要:

This paper introduces a new model and methodology for estimating the ability of NBA players. The main idea is to directly measure how good a player is by comparing how their team performs when they are on the court as opposed to when they are off it. This is achieved in a such a way as to control for the changing abilities of the other players on court at different times during a match. The new method uses multiple seasons' data in a structured way to estimate player ability in an isolated season, measuring separately defensive and offensive merit as well as combining these to give an overall rating. The use of game statistics in predicting player ability will be considered. Results using data from the 2008/9 season suggest that LeBron James, who won the NBA MVP award, was the best overall player. The best defensive player was Lamar Odom and the best rookie was Russell Westbrook, neither of whom won an NBA award that season. The results further indicate that whilst the frequently-reported game statistics provide some information on offensive ability, they do not perform well in the prediction of defensive ability.
