Multilevel model in lme4 and nlme
Dear list,
I am trying to fit some mixed models using packages lme4 and nlme.
I did the model selection using lmer but I suspect that I may have some
autocorrelation going on in my data so I would like to have a look using the
handy correlation structures available in nlme.
The problem is that I cannot translate my lmer model to lme:
mod1<- lmer(y~x + (1|a:b) + (1|b:c), data=mydata)
