Description
Variational Approximation for Joint Survival and Marker Models.
Description
Estimates joint marker (longitudinal) and and survival (time-to-event) outcomes using variational approximations. The package supports multivariate markers allowing for correlated error terms and multiple types of survival outcomes which may be left-truncated, right-censored, and recurrent. Time-varying fixed and random covariate effects are supported along with non-proportional hazards.
