[R] Power analysis and mixed model

[Dave Atkins]

Like Harold, I have also used simulation-based methods for power analyses, which 
I discuss (briefly) in the following article (with R code in an appendix):

Atkins, D. C. (2005).  Using multilevel models to analyze marital and family 
treatment data: Basic and advanced issues.  Journal of Family Psychology, 19, 
98-110.

However, depending on the nature of your design, it could be far easier to use 
Steve Raudenbush's Optimal Design software with menus and GUI, downloadable at:

Hi

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