Hello, I wanted to do proc mixed and I have 3 factors- treat group day. But while writing the model, I wrote e = treat group day treat*group group*day treat*group*day. I forgot to type treat*time. Because of this I got an significant interaction for treat*group*day. And the corrected by model I lost the significant difference for TGD interaction. Is it ok to use the model without treat*time? I already know that I have time effect. So for my results time is not a important criteria. So is that ok to leave out treat*time?
