摘    要:判别分析已越来越受到人们的重视并取得了重要的应用成果,但应用中存在着简单套用的情况,对判别分析的适用性、判别效果的显著性、判别变量的判别能力以及判别函数的判别能力的检验等问题重视不够。为了更好地应用判别分析,就应对判别分析进行统计检验并建立统计检验体系,统计检验体系应包括:判别分析适用性检验,判别效果显著性检验,判别变量的判别能力检验和判别函数的判别能力检验。

关 键 词:判别分析  假设检验  方差齐性检验

Abstract:As a method of multivariate data analysis, discriminant analysis has always been widely applied to many fields. However, there are many problems in the application of such an approach, for example, paying little attention to the fitness of discriminant analysis, the significance of discriminant analysis results, the significance of discriminant analysis variates, efficiency of discriminant functions, etc., not to mention the statistical testing; people tend to using this method blindly. In order to apply discriminant analysis better, it is necessary to make statistical test for discriminant analysis, and to establish statistical test system of discriminant analysis. Statistical test system of discriminant analysis includes that test of fitness of discriminant analysis, test of significance of discriminant results, test of the significance of discriminant analysis variates, test of efficiency of discriminant functions.
Keywords:discriminant analysis  hypothesis test  test for homogeneity of variance
