data distribution for lme
This is not really an R question -- it is statistics. In any case, you should do better posting this on the R-Sig-Mixed-Models list, which concerns itself with matters like this. However, I'll hazard a guess at an answer: maybe. (Vague questions elicit vague answers). Cheers, Bert

Hi folks, I am using the lme package of R, and am wondering if it is assumed that the dependent factor (what we fit for; y in many relevant texts) has to have a normal Gaussian distribution? Is there any margins where some skewness in the data is accepted and how within R itself one could check distribution of the data? Thanks, Peyman
