In a 4-class LGMM using a continuous outcome, I am trying to designate a specific class as the referent, so that covariates predict that class in relation to each of the others.
However, when I use starting values (mean values for the intercept and slope derived from a previous run), the appropriate class is never the 4th class (the referent). I have tried using starting values for all of the classes and for the 4th class alone.
In my searches of the discussion board, I have not been able to determine what I am doing wrong. How are starting values determined in this context? Any help is appreciated.
