数量化理论Ⅱ是和判别分析相对应的。判别分析是在自变量为定量变量的情况下,对个体进行判别;而数量化理论Ⅱ对自变量不作任何要求,既可以是定量的、也可以是定性的如:性别、职业等),且可兼有定量和定性变量。因此,可以说数量化理论Ⅱ是判别分析的推广。用数量化理论Ⅱ进行判别与判别分析的基本原理是一致的,都是在使同类的一些个体
Quantitative theory II corresponds to discriminant analysis. The discriminant analysis is to judge the individual when the independent variable is the quantitative variable; and the quantification theory II does not require any independent variable, either quantitative or qualitative, such as gender, occupation, etc.) It can have both quantitative and qualitative variables. Therefore, it can be said that quantification theory II is a generalization of discriminant analysis. The basic principles of discriminant analysis and discriminant analysis using quantification theory II are consistent, and they are all to make similar individuals.
