Hi,
 
I have a variable that gives weights to each case. Is there a way with lme() to specify weights ? I tried the "weights" argument but I think it is not the write place. The argument ask me for a varFunc object, which I don't know what it is!!
 
I know that the "weights" argument works well with lmer() but lmer() doesn't give the p-values for fixed effects, or at least I don't know how to get it from lmer().
 
Thanks,

François Maurice
