Boxing2 Data

This data set comes from purse information provided by the Nevada State Athletic Commission (NSAC) and the California State Athletic Commission (CSAC). The NSAC provided purse information on professional boxing matches in that state from 2009 to 2017. The CSAC provided purse information for the period June 2012 to December 2015 and its website provided purse information for 12 additional boxing cards held between 2016 and 2017, which are also included in the data set. After excluding female boxers and a few other minor exclusions, the result is an unbalanced panel of 1,212 boxers observed an average of 3.85 fights.本数据集源自内华达州体育委员会（Nevada State Athletic Commission, NSAC）与加利福尼亚州体育委员会（California State Athletic Commission, CSAC）提供的职业拳击赛事出场酬金信息。其中，NSAC提供了该州2009年至2017年职业拳击赛事的酬金数据；CSAC则提供了2012年6月至2015年12月期间的赛事酬金信息，其官方网站还披露了2016年至2017年间举办的额外12场拳击赛事的酬金数据，该部分内容亦被纳入本数据集。在剔除女子拳手及其他少量不符合要求的样本后，最终得到包含1212名拳手的非平衡面板数据，每名拳手平均被观测到3.85场比赛。
