In recent years, the joint models have been widely used for modeling the longitudinal and time-to-event data simultaneously.
In this study, we proposed an approach (PA) to study the longitudinal and survival outcomes simultaneously in heterogeneous populations.
PA relaxes the assumption of conditional independence (CI).
We also compared PA with joint latent class model (JLCM) and separate approach (SA) for various sample sizes (150, 300, and 600) and different association parameters (0, 0.2, and 0.5).
The average bias of parameters estimation (AB-PE), average SE of parameters estimation (ASE-PE), and coverage probability of the 95% confidence interval (CP) among the three approaches were compared.
In most cases, when the sample sizes increased, AB-PE and ASE-PE decreased for the three approaches, and CP got closer to the nominal level of 0.95.
When there was a considerable association, PA in comparison with SA and JLCM performed better in the sense that PA had the smallest AB-PE and ASE-PE for the longitudinal submodel among the three approaches for the small and moderate sample sizes.
Moreover, JLCM was desirable for the none-association and the large sample size.
Finally, the evaluated approaches were applied on a real HIV/AIDS dataset for validation, and the results were compared.
