A Simulated Data Set under Left Truncation and Right Censoring where Censoring can be before Truncation
Description
A simulated data set under left truncation and right censoring where censoring can be before left truncation.
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 censored event time X 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%; the censoring rate is 16.5%; P^*(C<Q) = 0.6057;
and the truth P^*(T>3) = 0.623955.
