Dear all, I have been searching ways to run power analysis for mixed-effects models. However, I have not been successful in the research. Today I would like to ask your help. As long as I see from my search, Martin Julien wrote a package called pamm for the power analysis. One of the limitations in the current version is that pamm cannot handle categorical fixed variables. Todd Jobes introduced his script to run power analysis for mixed-effects models (http://toddjobe.blogspot.co.nz/2009/09/power-analysis-for-mixed-effect-models.html). However, some parts of the script is beyond my knowledge. I am not sure if I can run power analysis with categorical variables either. Is there anybody who has run post hoc power analysis for mixed-effects models? If you have experiences, I would like to ask your help. Thank you very much for taking your time.
