Simulation estimates for bias (upper-left) and variance (upper-right) for Z(τ) = 1,X = 1, ΔAUC(bottom-left), and ΔR2 (bottom-right) for predicted probability P(T ≤ τ + 3|T > τ,Z(τ),X) from joint models (MM), (MMCox), (MSM), (MSMCox), (SMM), and landmark models (LSM3), (LSM4) fit to data structured as a longitudinal dataset, under a semi-Markov illness-death model with a single baseline covariate and inspection time marker measurement.
