lme and varFunc()
Dear R users,
I am currently analyzing a dataset using lme(). The model I use has the
following structure:
model<-lme(response~Covariate+TreatmentA+TreatmentB,random=~1|Block/Plot,method="ML")
When I plot the residuals against the fitted values, I see a clear
positive trend (meaning that the variance increases with the mean).
I tried to solve this issue using weights=varPower(),
