We investigate the predictability and persistence of individual and team performance (hot-hand effect) by analyzing the complete recorded history of international cricket. We introduce an original temporal representation of performance streaks, which is suitable to be modelled as a self-exciting point process. We confirm the presence of predictability and hot-hands across the individual performance and the absence of the same in team performance and game outcome. Thus, Cricket is a game of skill for individuals and a game of chance for the teams. Our study contributes to recent historiographical debates concerning the presence of persistence in individual and collective productivity and success. The introduction of several metrics and methods can be useful to test and exploit clustering of performance in the study of human behavior and design of algorithms for predicting success.
我们通过分析国际板球的完整记录历史,研究个人和团队表现(热手效应)的可预测性和持续性。我们引入了一种原始的表现连胜的时间表示法,该方法适合作为自激发点过程进行建模。我们确认了个人表现的可预测性和热手现象的存在,而团队表现和比赛结果则不存在这种现象。因此,板球对于个人来说是一项技巧性的运动,而对于团队来说则是一项机会性的运动。我们的研究为最近关于个人和集体生产力和成功的持续性存在的历史编纂辩论做出了贡献。引入几个指标和方法对于在研究人类行为和设计成功预测算法时检验和利用表现的聚类可能会很有用。
