Count-based football KPIs

Count-based metrics extracted from the 2016 UEFA Men’s European Football Championship and the 2017 UEFA Women’s Championship. Key metrics by player position and gender were extracted from match action logs and integrated as a single dataset. The resulting dataset of length $n = 4211$ contains 33 variables. The gender target variable is expressed as 1 for male players and 0 for female players. There are 2700 male instances and 1511 female instances. The dataset contains two categorical variables; match period is expressed as 1H for the first half, 2H for the second half, and E1, E2, and P for the two possible overtimes and the penalties respectively, player position in the team formation has the following options: Defender, Midfielder, Forward, Goalkeeper, Substitute Defender, Substitute Midfielder, Substitute Forward and Substitute Goalkeeper. Table \ref{tab:stats} shows the mean value and standard deviation per gender of each of the 30 numerical features of the dataset.

本数据集提取自2016年欧洲足球协会联盟（UEFA）男子欧洲足球锦标赛与2017年UEFA女子欧洲足球锦标赛的计数类统计指标。研究人员从比赛行为日志中提取了按球员场上位置与性别划分的核心指标，并整合为单一数据集。最终构建的数据集样本量为$n=4211$，共包含33个变量。性别目标变量以1标识男性球员，0标识女性球员；数据集中共包含2700条男性球员样本与1511条女性球员样本。本数据集包含两类分类变量：其一为比赛时段，其中1H代表上半场，2H代表下半场，E1、E2与P分别对应两次加时赛与点球大战；其二为球队阵型中的球员场上位置，可选取值包括后卫（Defender）、中场（Midfielder）、前锋（Forward）、守门员（Goalkeeper）、替补后卫（Substitute Defender）、替补中场（Substitute Midfielder）、替补前锋（Substitute Forward）与替补守门员（Substitute Goalkeeper）。表
