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
(I would like to have access to the value...
