说明：  判别分析又称“分辨法”，是在分类确定的条件下，根据某一研究对象的各种特征值判别其类型归属问题的一种多变量统计分析方法。其基本原理是按照一定的判别准则，建立一个或多个判别函数，用研究对象的大量资料确定判别函数中的待定系数，并计算判别指标。据此即可确定某一样本属于何类。
(Discriminant analysis, also known as "distinguished law" is classified under the conditions established, a multivariate discriminant ownership of its type statistical analysis method based on the value of the various features of a research object. The basic principle is based on a certain criterion to establish one or more discriminant function to determine the discriminant function coefficients to be determined in the study of large amounts of data, and calculate the discrimination index. Accordingly to determine whether a sample belongs to any category.)
