5. Consider the following 4 models 1. Y = 80+ B.X + II. Y = Be + BX +3,X+ III. Y = 8 + 8 X + B,X+B3X + IV. Y = R + B,X + B,X? + B,X*+B.X+ +. (a) Set a random seed and compute the LOOCV errors that result from the fitting the above models using least squares, (b) Use another random seed, repeat (a) and compare these findings with (a). (c) Which of the four models has the smallest LOOCV error? Is this surprising? (d) Comment on the statistically significant predictors found from the least squares fits. Are they in agreement with the LOOCV results?
