Regarding multiple linear regression analysis:

a. What sum of squares is made as small as possible when finding the best-fitting plane based on the method of least squares?

b. What do we call the best-fitting plane that is obtained by the method of least squares?

c. What do we call the act of using a multiple linear regression equation to make predictions for values of the predictor variables that are outside the region of the observed values of the predictor variables?
