Background: 30 participants, 4 tests (1,2,3,4) at 7 frequencies (125,250,500,1000,2000,4000,8000 Hz) in 2 rooms (a , b). Model: mixed effects model compares test 1 at frequency 8000 (frequency 7) to other tests. The basic question is to compare test 1 to test 4 at all frequencies. Code: proc mixed data=roomb empirical method=ML; class User_ID Ears; model Y_= Test2 Test3 Test4 Freq1 Freq2 Freq3 Freq4 Freq5 Freq6 Test4*Freq1 Test4*Freq2 Test4*Freq3 Test4*Freq4 Test4*Freq5 Test4*Freq6/s outpm=predict; random intercept /subject = User_ID; random intercept /subject = Ears(User_ID); run; I want to run bonferonni's correction test, but I am unable to. Could someone please help me?
