plot_trajectory_mult

Plots a grid of longitudinal trajectories for a multivariate model.
The grid displays each outcome (rows) and each latent group (columns).
Individual trajectories are colored by their assigned group and faded,
with the specific group highlighted and its average polynomial curve overlaid.

Estimation of group-based trajectory models, including finite mixture models for longitudinal data,
supporting censored normal, zero-inflated Poisson, logit, and beta distributions,
using expectation-maximization and quasi-Newton methods, with tools for model selection,
diagnostics, and visualization of latent trajectory groups,
