Hello,
So after using the mixed procedure, I get "." for the F value and p-value for my interaction term. Does this mean the interaction term is insignificant or did I do something wrong?
Please show your code and say more about the variables. You ought to get at least one value, but some will be blank. See the examples in the documentation for PROC MIXED
My code:
proc mixed;
class side event subj;
model FA = event side event*side;
repeated event / type=cs subject = subj;
title2 "MIXED";
run;
My results:

I'm just wondering if the missing values for side*event means there's no interaction or if something is wrong with the code/data. Thanks~
Thanks~
