判别分析在有的数理统计书中称为分辨分析或分辨法,它是根据观测到的数据资料,对所研究的对象进行分类,即判别样品所属类型的一种统计方法。它是构成一个或一组判别函数,根据已有观测资料中各类主要特征建立判别方程,确定判别函数,再对新加入的样本进行分辨,判别它所属的种类、级别。因此,判别分析的基本思想是根据一个个体,或一个样本的若干特性的观

Discriminant analysis in some mathematical statistics called resolution analysis or resolution method, which is based on the observed data, the classification of the object under study, that is, to determine the sample belongs to a statistical method. It constitutes one or a group of discriminant functions. Based on the main features of the observed data, a discriminant function is established to determine the discriminant function, and then the newly added samples are distinguished to determine the type and level to which they belong. Therefore, the basic idea of ​​discriminant analysis is based on the concept of an individual, or a number of characteristics of a sample
