piecewise_exponential: Transition Hazards for Piecewise Exponential Event Times

In simIDM: Simulating Oncology Trials using an Illness-Death Model

Transition Hazards for Piecewise Exponential Event Times

Description

This creates a list with class TransitionParameters containing hazards, time intervals and Weibull rates for piecewise exponential event times in an illness-death model.

Usage

piecewise_exponential(h01, h02, h12, pw01, pw02, pw12)

Arguments

h01	(⁠numeric vector⁠) constant transition hazards for 0 to 1 transition
h02	(⁠numeric vector⁠) constant transition hazards for 0 to 2 transition
h12	(⁠numeric vector⁠) constant transition hazards for 1 to 2 transition
pw01	(⁠numeric vector⁠) time intervals for the piecewise constant hazards h01
pw02	(⁠numeric vector⁠) time intervals for the piecewise constant hazards h02
pw12	(⁠numeric vector⁠) time intervals for the piecewise constant hazards h12

Value

List with elements hazards, intervals, weibull_rates and family (piecewise exponential).

Examples

piecewise_exponential(
  h01 = c(1, 1, 1), h02 = c(1.5, 0.5, 1), h12 = c(1, 1, 1),
  pw01 = c(0, 3, 8), pw02 = c(0, 6, 7), pw12 = c(0, 8, 9)
)
