simulation_nofrailty {survregVB} | R Documentation |
Simulated data without shared frailty effects to model unclustered time-to-event data.
Description
Simulated data without shared frailty effects to model unclustered time-to-event data.
Usage
simulation_nofrailty
Format
A dataframe with 300 observations.
- x1
Continuous covariate from
N(1, 0.2^2)
- x2
Binary covariate from
Bernoulli(0.5)
- Time
True survival time
- Time.10
Observed survival time accounting for uniformly distributed right censoring time from
uniform(0,48)
- Time.30
Observed survival time accounting for uniformly distributed right censoring time from
uniform(0,17)
- delta
Event indicator for uncensored data (always 1 in this simulation.)
- delta.10
Event indicator for T.10 (1 = event, 0 = censored).
- delta.30
Event indicator for T.30 (1 = event, 0 = censored).
