摘要
在判别分析中,无论采用那种判别方法,错判是不可避免的.错判的来源主要有2方面,一是各类总体的均值相近,另一是各总体的协方差的非齐性,针对各种原因给出相应的修正原则和方法.
In discriminant analysis mistaken discfiminant is inescapable whatever discriminant method is applied, Mistaken discriminant results mainly in two aspects, One is that the average value of each collectivity is approximately equal, the other is covariance of each collectivity is non-homogeneous. In this paper, the corresponding adjustment law and method for different reasons are presented.
