Gbtm group based trajectory modelling

[Tommaso Salvitti]

Good evening If we have 6 variables and about 100 subjects, is it possible to use GBMTM, the multivariate latent class analysis model? I have 3 time points... my idea is to assume a maximum of 3 groups and polynomials up to order 1.
Thank you so much for everything and sorry for the inconvenience
Please help me!!!
all the best
