Hi all, Could someone please tell me if we have to group data in the units with a command such "factor()" or "groupedData()" before using the functions glmmPQL or GLMM. I didn't do that and at first my results seem OK, but I'd like to solve this doubt. Thanks in advance, Alex __________________________________________________________________________ Acabe com aquelas janelinhas que pulam na sua tela.
