For example, in the SAT case study, you might want to predict a student's university grade point average on the basis of their High-School GPA (\(HSGPA\)) and their total SAT score (verbal + math). Multiple Linear Regression is an analysis procedure to use whe n more than one explanatory variable is included in a “model”. For example, consider the cubic polynomial model which is a multiple linear regression model with three regressor variables.

There are many books on regression and analysis of variance. If the truth is non-linearity, regression will make inappropriate predictions, but at least regression will have a chance to detect the non-linearity. (3.2) may often still be analyzed by multiple linear regression techniques. Second, multiple regression is an extraordinarily versatile calculation, underly-ing many widely used Statistics methods.
