Latent class analysisPTSDPrevious models of depression outcomes have been limited by symptom heterogeneity within populations. This study conducted a retrospective analysis using latent growth mixture models to identify heterogeneous trajectories within a clinical population, subsequently developing machine ...
If the discrete-valued variable is observed, then eqn [18] reduces to a linear regression model with both main effects and time-interaction effects as yielded by the levels of that variable. Therefore, the defining feature of the latent growth model in eqn [18] is that the class to which...

Hello I am conducting the latent class growth mixture model for my study .This study uses data from the longitudinal cohort. Data includes 4 different phases.Phase 1 has a span of (2003-2006) and is following at 3 subsequent phases.we aimed to identify different patterns of BMI I WANTto ...
I am thinking of a random intercepts and slopes model (for longitudinal data), but would like to have random slopes follow a mixture normal (latent class), while keep random intercept a regular normal. Can growth mixture model be applied in this situation?
