The impact of horse age, sex and number of riders on horse performance in British Eventing horse trials

The data is publicly accessible on the British Eventing website (https://www.britisheventing.com/compete/fixtures-and-results). The master dataset includes scores from all horses competing between 2008 and 2018. The age at which a horse competed is calculated using the year of birth of the horse, and the year of the competition. To create dA, the lowest position for each horse is selected for each class in which they competed. To create dB, the lowest score for each individual horse/rider combination is selected. Both dA and dB are split into the major classes of British Eventing competition.

本数据集可于英国三项赛（British Eventing）官方网站（https://www.britisheventing.com/compete/fixtures-and-results）公开获取。主数据集涵盖2008年至2018年间所有参赛马匹的赛事得分数据。参赛马匹的年龄通过其出生年份与赛事举办年份计算得出。为构建数据集dA，需针对每匹马参与的每个赛事组别，选取其取得的最低名次。为构建数据集dB，需针对每一组独立的马匹/骑手搭档，选取其取得的最低得分。数据集dA与dB均按照英国三项赛的主流赛事组别进行划分。
