help on lme and variance estimation
Hi all, I have a random effect model that can be written as y_{ij} = \beta +\alpha_i+ \epslion_{ij} where \alpha_i ~ N(0,\sigma^2_effect) and \espilon_{ij} ~ N(0,\sigma^2_error) and i compute res<-lme(data~1,data=Data,random=~1 | veci) The estimation of \sigma_error is given by res$sigma but I don't understand how i can find the estimation of \sigma _effect with the object res...
