WebApr 21, 2024 · One promising approach that can be used to identify multiple unique PRO trajectories in heterogeneous clinical populations is Growth mixture modelling (GMM; a.k.a. latent variable mixture models), which is suitable when subgroups of patients with different trajectories are expected and grouping variables are not known a priori.

Members of class 2 are expected to have 0.8 accidents per year. Class membership certainly has to do with expected accident rate, and we take that as evidence that the classes provide some indication of riskiness.
