WebThe CP statistic (called Mallow’s C(P)) is more interesting than R2, since it can be used to determine the best model. (Whether the model so determined is really the best is a matter of interpretation.) Mallow’s CP is calculated as C(P) = (k −p)∗[F(p)−1]+p, where k = number of possible original predictors, and F(p) is the F-statistic ...
