Diagnostic criteria for judging the adequacy of the final model

Trajectory group	AvePP	OCC	P	π
Group 1	0.88	20.2	0.257	0.251
Group 2	0.89	35.7	0.188	0.187
Group 3	0.91	50.6	0.168	0.168
Group 4	0.85	50.5	0.094	0.098
Group 5	0.89	55.0	0.130	0.131
Group 6	0.95	321.9	0.060	0.060
Group 7	0.86	52.7	0.103	0.105

AvePP: average posterior probability; OCC: odds of correct classification; p: actual proportion of subjects assigned to each trajectory group using the maximum probability rule; π: the posterior probability of group membership estimated by the model
