Dear R users,
I have this 2 models that fit to my data:
M3varI <- update (M3, weights=varIdent(form= ~ 1|SITE))
M3AR1<-update(M3,correlation=corAR1())
The first one, updates my M3 so that I can account for the variance
structure of random erros.
The second one, updates my M3 so that I can account for the
correlation structure of random errors.
How can I put them toghether in one final model?
I have tryed it using gls but I could not do it.
Could you please help me o this?
Bets regards,
