Graduation Rates. Refer to Exercise B.86 on page B-118, where we considered the
- a. Use the maximum-R2 criterion to obtain a regression equation for these data.
- b. Use the adjusted-R2 criterion to obtain a regression equation for these data.
- c. Use the Mallows’ Cp criterion to obtain a regression equation for these data.
- d. Do the three methods used in parts (a), (b), and (c) yield the same final regression equation?
