Document Summary

Analysis of variance, or more commonly anova, helps to analyze both within-group and between-group variance. Indicator variables are helpful when including categorical variables into a regression model. 1 plot ( edu , log . wrate , col =7 , xlab = " e d u c a t i o n " , ylab = " log hourly rate " ) R will automatically create these indicator variables by performing the normal call to the linear model function (edu is a categorical variable). 1 reg
