In multiple regression analysis, the total variation in the response variable is separated into two components: regression variation (also called model variation) and residual variation (also called error variation). The regression variation is the variation in the response variable that is explained by the predictors in the model. The residual variation is the variation that is not explained by the predictors, and is assumed to be random error. Therefore, the ANOVA table for a multiple regression model separates the total variation into regression and residual variation.
