Bayesian Joint Modeling Analysis of Longitudinal Proportional and Survival Data

open access: yesMathematics, 2023
This paper focuses on a joint model to analyze longitudinal proportional and survival data. We utilize a logit transformation on the longitudinal proportional data and employ a partially linear mixed-effect model. With this model, we estimate the unknown
