Data generation for the Cox proportional hazards model with time-dependent covariates: A method for medical researchers [PDF]

Statistics in Medicine, 2013
The proliferation of longitudinal studies has increased the importance of statistical methods for time-to-event data that can incorporate time-dependent covariates. The Cox proportional hazards model is one such method that is widely used.
