Transition hazards for exponential event times

Source: R/transitionParameters.R

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

exponential_transition(h01, h02, h12)

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.

Value

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