Group-based multi-trajectory modeling

[GregLee]

Hi all - in the past the Proc Traj plug-in and macros have been the natural method for undertaking group-based multi-trajectory modeling (i.e. latent profile analysis with multiple continuous input variables measured longitudinally). I am now trying to understand is my latest PROC FMM version can't in fact do this. Any guidance? There's nothing like that in the PROC FMM examples.
