Repeated measures ANOVA for unbalanc
Well ... 1. Try the latest version of lmer/lme4 and see for yourself. I think the answer is still no. 2. If 1 is true, then I think you need to ask whether you **want** to use a package that returns p values and se's, whether it exists or not. Cheers, Bert On Thu, Nov 21, 2013 at 2:07 PM, John Sorkin

Colleagues,
The last time I thought about using lmer to run an unbalanced repeated measures ANOVA, I found that the package did not return p values or SEs. I believe this was because Professor Bates had important questions about the theory behind the required computations and was in the process of developing a new, improved algorithm. Has this situation changed? Has Prof. Bates, or anyone else, implemented a repeated measures ANOVA package for R that can be perform unbalanced repeated measures ANOVA and which produces valid p values and SEs? If so, what is the name of the package?
Thank you,
John
