Dear Jim,

I have never faced problems with estimation of interaction effects in the MIXED procedure. I do it like this, where 'z1' interacts with 'x2':

MIXED y WITH x1 x2 z1 /FIXED = intercept x1 x2 z1 x2*z1 /METHOD = REML /PRINT = SOLUTION TESTCOV /RANDOM INTERCEPT x2 | SUBJECT(CLASSID) COVTYPE(UN).

Best, Henrik
