Simulated Sample Dataset for Demonstration
A simulated data frame with covariates named
ID: Subjects identification;
time: Event or censoring time;
event: Event indicator, 1 = event, 0 = censored;
group: Treatment group indicator;
x1: Continuous variable.
A data frame with 500 rows and 5 variables.
The sample dataset is originally simulated by the thinning method developed by Lewis and Shedler (1979) and further processed for a better demonstration purpose. See Fu et al. (2014) for details also.
