I am trying to determine the best model for my outcomes in SAS 9.2 mixed and glimmix- does anyone know if I want to test the effects of removing var1-do I need to remove it from BOTH the class and model statements or just one?
proc mixed var1;
class var1 var2;
model var2 var3 var4;
random intercept var6 / var 7;
run;
OR
proc mixed var1;
class var2;
model var2 var3 var4;
random intercept var6 / var 7;
run;
Thanks!!
