By: X. Song n, M. Davidian n  & A. Tsiatis n

author keywords: informative censoring; mixed model; proportional hazards; SNP density; survival
MeSH headings : Anti-HIV Agents / therapeutic use; Biometry / methods; Computer Simulation; Disease Progression; HIV Infections / drug therapy; Humans; Likelihood Functions; Longitudinal Studies; Monte Carlo Method; Proportional Hazards Models; Randomized Controlled Trials as Topic / methods
TL;DR: This work proposes a likelihood-based approach that requires only the assumption that the random effects have a smooth density, and implementation via the EM algorithm is described, and performance and the benefits for uncovering noteworthy features are illustrated. (via Semantic Scholar)
