WebThe whole model F test (test of the useful of the model) tests whether the slopes on all variables in multiple regression are zero, i.e., it tests whether the multiple regression is more useful for prediction than just ignoring the X’s and using to predict Y. For testing whether one slope in multiple regression is zero, we can use the t-test.
