Semiparametric Latent Class Analysis of Recurrent Events

Efficient R package for latent class analysis of recurrent events, based on the semiparametric multiplicative intensity model by Zhao et al. (2022) . SLCARE returns estimates for non-functional model parameters along with the associated variance estimates and p-values. Visualization tools are provided to depict the estimated functional model parameters and related functional quantities of interest. SLCARE also delivers a model checking plot to help assess the adequacy of the fitted model.

SLCARE

Recurrent event data frequently arise in biomedical follow-up studies. The concept of latent classes enables researchers to characterize complex population heterogeneity in a plausible and parsimonious way. SLCARE implements a robust and flexible algorithm to carry out Zhao et al.(2022)’s latent class analysis method for recurrent event data, where semiparametric multiplicative intensity modeling is adopted. SLCARE returns estimates for non-functional model parameters along with the associated variance estimates. Visualization tools are provided to depict the estimated functional model parameters and related functional quantities of interest. SLCARE also delivers a model checking plot to help assess the adequacy of the fitted model.
