Simulated Sample Dataset for Demonstration
Description
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.
