论文摘要
使用从官方锦标赛网站获得的公开可用数据，使用非参数统计技术，Wilcoxon的签名排名测试和机器学习的一项决策规则技术，使用从官方锦标赛网站获得的公开数据分析了在2019年橄榄球世界杯上取得成功的绩效指标。我们的统计结果发现，发现球的有效性（渗透对手增益线的球射击的百分比）和获得的总表格（踢仪和携带仪表）在比赛的两个阶段都取得了成功，并且在小组阶段取得了成功的指标（在集体阶段中取得了成功（占主导地位），使更多的舞台竞选，使更多的舞台逐步竞争，并取得了更大的贡献，并取得了更大的贡献，并取得了更大的贡献），并取得了更大的贡献）。我们使用Ripper的结果发现，低球和较低的排队成功百分比共同在小组赛阶段取得了贡献，同时赢得了较低的跑跑并延续了收益线，足以在比赛的季后赛中获胜。结果强调了团队需要将他们的比赛策略从小组赛阶段调整到比赛中的季后赛阶段，以取得成功。
Performance indicators that contributed to success at the group stage and play-off stages of the 2019 Rugby World Cup were analysed using publicly available data obtained from the official tournament website using both a non-parametric statistical technique, Wilcoxon's signed rank test, and a decision rules technique from machine learning called RIPPER. Our statistical results found that ball carry effectiveness (percentage of ball carries that penetrated the opposition gain-line) and total metres gained (kick metres plus carry metres) were found to contribute to success at both stages of the tournament and that indicators that contributed to success during the group stages (dominating possession, making more ball carries, making more passes, winning more rucks, and making less tackles) did not contribute to success at the play-off stage. Our results using RIPPER found that low ball carries and a low lineout success percentage jointly contributed to losing at the group stage, while winning a low number of rucks and carrying over the gain-line a sufficient number of times contributed to winning at the play-off stage of the tournament. The results emphasise the need for teams to adapt their playing strategies from the group stage to the play-off stage at tournament in order to be successful.
