在之前的讨论中，自变量都是连续变量或定量变量。在很多情况下，这个限制太大了。本章介绍回归模型中分类变量或类变量的使用。类变量的使用扩大了回归的范围，包括经典的方差模型分析和同时包含连续变量和类变量的模型，如协方差模型分析和检验组间回归齐性的模型。
In all previous discussions, the independent variables were continuous or quantitative variables. There are many situations in which this is too restrictive.This chapter introduces the use of categorical or class variables in regression models. The use of class variables broadens the scope of regression to include the classical analysis of variance models and models containing both continuous and class variables, such as analysis of covariance models and models to test homogeneity of regressions over groups.
