Bayesball:一个贝叶斯层次模型,用于评估美国职业棒球大联盟的防守

Bayesball: A Bayesian hierarchical model for evaluating fielding in major league baseball

Shane T. Jensen, Kenneth E. Shirley, Abraham J. Wyner

摘要:

统计建模在棒球中的应用最近在媒体和学术界都受到了极大的关注。我们专注于一个相对未充分探讨的主题:使用统计模型的分析,基于高分辨率的数据组成的现场位置的击球防守。我们结合空间建模与层次贝叶斯结构,以评估个人的外野手的表现,同时在每个位置的外野手之间共享信息。我们目前的结果在四个赛季的MLB数据(2002- 2005年),并比较我们的方法与其他的外场评估程序。

英文摘要:

The use of statistical modeling in baseball has received substantial attention recently in both the media and academic community. We focus on a relatively under-explored topic: the use of statistical models for the analysis of fielding based on high-resolution data consisting of on-field location of batted balls. We combine spatial modeling with a hierarchical Bayesian structure in order to evaluate the performance of individual fielders while sharing information between fielders at each position. We present results across four seasons of MLB data (2002--2005) and compare our approach to other fielding evaluation procedures.
