TESTING THE STRENGTH OF THE MULTIPLE REGRESSION MODEL

TESTING THE STRENGTH OF THE MULTIPLE REGRESSION MODEL. Test 1: Are Any of the x’s Useful in Predicting y?. We are asking: Can we conclude at least one of the ’s (other than  0 )  0? H 0 :  1 =  2 =  3 =  4 = 0 H A : At least one of these ’s  0  = .05.
