In keaven/simtrial: Clinical Trial Simulation

Time-to-event data example 5 for non-proportional hazards working group

Description

Survival objects reverse-engineered datasets from published Kaplan-Meier curves. Individual trials are de-identified since the data are only approximations of the actual data. Data are intended to evaluate methods and designs for trials where non-proportional hazards may be anticipated for outcome data.

Usage

data(Ex5widening)

Format

Data frame with 4 variables:

id

sequential numbering of unique identifiers

month

time-to-event

event

1 for event, 0 for censored

trt

1 for experimental, 0 for control

References
