Multiple linear regression, which extends simple linear regression to any

number of predictor variables, is covered in Section 1.6. General linear models and least squares estimator are presented using matrix algebra. Analysis

of variance, R2 (multiple correlation coefficient), and the extra sum of squares

principle are included.
