本文运用判别分析方程式,分析影响CBA联赛比赛胜负的关键数据指标。研究结果表明:常规赛中影响比赛胜负的关键数据指标是2分球、3分球命中率、防守篮板数和助攻数4项数据指标;季后赛中影响比赛胜负的关键数据指标是2分球命中率、防守篮板数和助攻数3项数据指标。在两队最终得分相接近的比赛中,判别方程结果显示无合适数据指标是影响比赛胜负的关键数据指标;在两队最终得分相差不大的比赛中,防守篮板数和助攻数是影响比赛胜负的关键数据指标。
In this paper, discriminant analysis equations are used to analyze the key data indicators that affect the outcome of CBA matches. The results show that the key data indicators that influence the outcome of the competition in the regular season are 4-point data such as 2-point shooting, 3-point shooting, defensive rebounding and assists. The key data indicators influencing the outcome of the match in the playoffs are 2-point shooting, defensive rebounds and assists 3 data indicators. In the game where the two teams finally score close, the discriminant equation shows that the unsuitable data index is the key data index that affects the outcome of the match. In the competition where the final scores of two teams are not much different, the defensive rebounds and assists affect the competition Winning the key data indicators.
