Transition Hazards for Weibull Distributed Event Times

Source: R/transitionParameters.R
weibull_transition.Rd

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

Usage

weibull_transition(h01 = 1, h02 = 1, h12 = 1, p01 = 1, p02 = 1, p12 = 1)

Arguments

h01

(positive number)
transition hazard for 0 to 1 transition

h02

(positive number)
transition hazard for 0 to 2 transition

h12

(positive number)
transition hazard for 1 to 2 transition

p01

(positive number)
rate parameter of Weibull distribution for h01

p02

(positive number)
rate parameter of Weibull distribution for h02

p12

(positive number)
rate parameter of Weibull distribution for h12

Value

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

Examples

weibull_transition(h01 = 1, h02 = 1.3, h12 = 0.5, p01 = 1.2, p02 = 1.3, p12 = 0.5)
