摘要
本文介绍用极大似然估计对Logistic判别分析中的变量进行逐步筛选的方法,筛选过程是在对判别系数作似然比检验的基础上进行的,在变量向前选入与向后剔除的每一步中都用到这种检验;最后举出了应用实例。
A stepwise selection of variable for logistic discriminant, analysis using maxunum likelihood estimation is introduced here. The selection procedure is based on likelihood ratio tests for the discriminant coefficients. These tests are used in a forward selection and a backward e tion at each step. The use of the selection procedure is illustrated by several examples.
