simu {truncAIPW}

A Simulated Data Set under Left Truncation but No Right Censoring

Description

A simulated data set under left truncation but no right censoring. The left truncation time and the event time are dependent via the two covariates ‘Z1’ and ‘Z2’. Under the data generating mechanism, the conditional distribution of the event time given covariates follows a Cox proportional hazards model in the full data, and the conditional distribution of the left truncation time given covariates follows a Cox proportional hazards model on the reversed time scale in the full data. The truncation rate is 29.5%; and the truth P^*(T>3) = 0.5755753.
