Example data matrix
Description
A matrix containing data from a clinical trial with a treatment arm and a control arm, as well as data from an external control. In this simulated dataset, the true hazard ratio (HR) for the time-to-event endpoint comparing the experimental treatment to the control treatment is 0.70. The true odds ratio (OR) for the binary response endpoint comparing the experimental treatment to the control treatment is 1.20.
Usage

- cov1
0/1, baseline covariate
- cov2
0/1, baseline covariate
- cov3

- status
0/1, indicator for event status (1 = had event, 0 = did not have event)
- cnsr
