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 the joint models (MM), (MMCox), and landmark models (LM1–LM4), under a Markov illness-death model with a single baseline covariate and continuously observed marker measurement.
