Simulated Sample Dataset for Demonstration

Source: R/data.R
simuDat.Rd

A simulated data frame with covariates named ID, time, event, group, x1, and gender, where

  • ID: Subjects identification;

  • time: Event or censoring time;

  • event: Event indicator, 1 = event, 0 = censored;

  • group: Treatment group indicator;

  • x1: Continuous variable.

  • gender: Gender of subjects.

Format

A data frame with 500 rows and 6 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. (2016) for details also.
