Hello everybody
I have done a generalized linear model (glm-function) with a binary
response variable (presence/absence) and two explanatory variables
(including the interaction term (model-glm(x~factor1*factor2,
family=quasibinomial)). The interaction is what we are mainly
interested in

Hi
Is there any way to compute power analysis for a mixed model ?

Julien,
You could write your Linear Mixed Model as a General Linear Multivariate
Model (GLMM) and use the power

Hi

I haven't seen a reply to this post, and you may have moved beyond
this question by now, but I will nevertheless offer one brief question:
Have you looked at 'simulate.lme'? This might simplify coding your
power analysis.
Hope this helps.
