Hi List,
I'm having this problem when trying to use the PREDICT function.
Here is a way to reproduce the error
library(REEMtree)
data(simpleREEMdata)
REEMresult<-REEMtree(Y~D+t+X, data=simpleREEMdata, random=~1|ID/D)
predict(REEMresult, simpleREEMdata, id = simpleREEMdata$ID/simpleREEMdata$D,
EstimateRandomEffects=TRUE)
As far as I understand the problem is that I'm not being able to specify
correctly the number of groups created in the random structure of the model
(~1|ID/D).
Does anybody knows how to FIX this ?
