dropping interaction terms
It sounds like the question is controversial. Yes, I'll post it on cross validated. Thanks!

This is really a broad linear modeling question rather than one that applies specifically to mixed models. Can I suggest that you try CrossValidated [https://stats.stackexchange.com] ? (Be prepared for a variety of opinions ...) cheers Ben Bolker On 2018-06-06 12:45 PM, Cristiano Alessandro wrote:
Dear all,
I have a simple design with two factors (each with two levels) and their
interaction term. I am analyzing it with mixed models.
The interaction term is not significant. Do I need to fit another model
without the interaction term before performing post-hoc tests, or is it
more appropriate to perform post-hoc tests on the full model with the
non-significant interaction term?
Thanks for your help
Best
Cristiano
