13.4 points Q In multiple regression, rather than using R2 as a measure of model "fit,\" we use Rzadj. The formula for Rzadj is: (17R2)(N71) R2 :17 Nip adj The term p is the number of coefcients estimated in the model. So if, for example, we are using two predictors, p will be equal to 3, as we also have to account for the intercept. For a model with four predictors (X1, X2, X3 and X4), p will be equal to 5. Suppose we have estimated, using 60 observations, a multiple regression model with three predictors (X1, X2 and X3). lfthis model's R2 is equal to 0646, what will its Rzadj be equal to?
