I have been playing with lme fitting different kinds of model. I am puzzled by the estimates associated with $modelStruct and I have no idea what they are? e.g if I fit a random intercept model using the following fit.0<-lme(y~time,random=list(subject=pdIdent(~1))) The coef(fit.0$modelStruct) produces
coef(fit.0$modelStruct)
reStruct.subject
0.4758451
....
For an explanation, see http://markmail.org/message/e2bn7wlwci3z4a75 (and please post your examples with test data, or with reference to nlme data (data =Machines comes close). Dieter
