CBA联赛近三年参赛球队成绩与其外援技术发挥的典型相关分析

Canonical Correlation between Teams' Performance Characteristics and Foreign Aids' Technical Characteristics in CBA of the Last Three Years

运用文献资料、数理统计、多元线性回归分析、典型相关分析等方法,对2007至2010年三届CBA联赛各届球队与外援的技术统计指标进行量化,研究其相关性,并得到各自的第一典型变量。研究表明:外援的各项技术指标与所在球队成绩指标的第一典型相关系数达到0.025的显著水平;反映外援技术特征的典型变量主要由出场次数决定;反映球队成绩特征的典型变量主要由胜率决定,出场次数和胜率是正相关的。

By using methods of documentation,mathematical statistics,correlation,canonical correlation and so on,and quantizing the technical statistic indexes of CBA teams and foreign aids from 2007 to 2010,we get their correlation and the first canonical variable of each other.What can be found is as follows： The teams＇ and foreign aids＇ first canonical correlation coefficient of technical index is up to 0.025-level significance;the technical characteristics canonical variable of foreign aids is determined by games played;The canonical variable that affects teams＇performance characteristics mainly is determined by winning-rate;The relationships of games played and winning-rate are both positive correlation.
