Chapter 12, Problem 99E(choose chapter or problem)
Use the football data in Exercise 12-21 to build regression models using the following techniques:
(a) All possible regressions. Find the equations that minimize \(\mathrm{MS}_{\mathrm{E}}\) and that minimize \(\mathrm{C}_{\mathrm{p}}\).
(b) Stepwise regression.
(c) Forward selection.
(d) Backward elimination.
(e) Comment on the various models obtained. Which model seems “best,’’ and why?
