simuDat: Simulated Sample Dataset for Demonstration

Description

A simulated data frame with covariates named ID, time, event, group and x1, where
  • ID: Subjects identification;
  • time: Event or censoring time;
  • event: Event indicator, 1 = event, 0 = censored;
  • group: Treatment group indicator;
  • x1: Continuous variable.

Arguments

Format

A data frame with 500 rows and 5 variables.

Details

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.
