Multiple Regressions
So far we have learned about simple regression (with one predictor
variable). Most of the time in practical research, we have to deal
with multiple predictors. In such cases, we conduct multiple
regression analysis. Multiple Regression equation is simply the
extension of simple regression equation
Recall the simple regression equation:
̂
Thus, the generalize form of multiple regression equation is
̂
Where b is the coefficient of each predictor variable
Example: Suppose we were interested in predicting freshman GPA
using High School percentage, entrance exam score, number of
extra curriculum activities, etc.
