摘要
相应于一元方差分析,总的多元方差一协方差阵可以剖分成组内和组间方差—协方差阵两部分。本文用方差—协方差阵的行列式值代表其异程度,定义多元重复力为广义的组内相关系数。在此基础上提出多元偏重复力的概念。
Total multivariate variance——covariance matrix may be derided into treatments and error variance matrices cooresponding to the analysis of variance. Using determinants as its changing range, the generalized correlation can be defined in this paper as multivariate repeatability to provide the concept of multivariate subrepeatability.
