棒球投掷能力的评价
Evaluating Throwing Ability in Baseball
摘要：
本研究以美国职棒大联盟外野手与接球手的投球能力为研究对象，进行量化分析。我们使用详细的比赛事件数据，以表格的成功和失败的事件，在外野手和捕手投掷机会。我们将每个赛季每个球员的成功或失败都归因于一个运行贡献。我们使用四个赛季的数据来估计整体投掷能力的每个球员使用贝叶斯分层模型。该模型允许我们根据每个玩家的机会数量将单个玩家的估计值缩小到总体平均值。我们使用这个模型的球员能力的后验分布，以确定具有显着的积极和消极的投掷贡献的球员。
英文摘要：
We present a quantitative analysis of throwing ability for major league outfielders and catchers. We use detailed game event data to tabulate success and failure events in outfielder and catcher throwing opportunities. We attribute a run contribution to each success or failure which are tabulated for each player in each season. We use four seasons of data to estimate the overall throwing ability of each player using a Bayesian hierarchical model. This model allows us to shrink individual player estimates towards an overall population mean depending on the number of opportunities for each player. We use the posterior distribution of player abilities from this model to identify players with significant positive and negative throwing contributions.
