Hi,

Firstly, I'm sorry if this question has been asked (and answered) before
(although I couldn't find it). I'm doing my analysis using logit mixed
models (family = binomial(link = "logit"), glmer model) and I was wondering
if there was a way to calculate power for my final model. I have looked over
the web and all I can find are programs and simulations for linear mixed
models with a continuous outcome, but not if the outcome is only 0's and
1's. Is there a way for me to calculate power for this model?

Thank you very much,

Evelien

Hi Evelien & List,

A very recent publication might answer your question:

Best,
Paul
