pw_exp_sim function

Simulates time-to-event outcomes.

Simulation of time-to-event outcomes using the piecewise constant hazard exponential function.

pw_exp_sim(hazard, n, maxtime = NULL, cutpoint = NULL)

Arguments

• hazard: vector. The constant hazard rates for exponential failures.
• n: scalar. The number of outcomes for simulation.
• maxtime: scalar. maximum time before end of study.
• cutpoint: vector. The change-point vector indicating time when the hazard rates change.

Returns

a dataset with simulated follow-up time (time) and respective event indicator (1 = event, 0 = censoring)

Examples

pw_exp_sim(c(0.02, 0.01, 0.005), 100, 100, c(10, 20))
          pw_exp_sim(0.015, 100, 100)
