%description
Provides tools to fit joint models of multivariate longitudinal data and
time-to-event data for dynamic prediction. It allows the joint prediction
of both future time-to-event outcomes and future longitudinal outcomes
conditional on survival. The models accommodate irregularly measured
longitudinal data and competing risks outcomes. The use of the backward
joint model enables fast and efficient computation, especially for
applications with large sample sizes and many longitudinal variables.
Methods without competing risks are described in Shen and Li (2021)
<doi:10.1002/sim.9037>, and their extension to competing risks is
described in Li et al. (2026) <doi:10.1007/s10985-026-09725-x>.
