Probability of Remaining in Progression Between Two Time Points for Different Transition Models

Usage

log_p11(transition, s, t)

Arguments

transition: (TransitionParameters)
see exponential_transition(), weibull_transition() or piecewise_exponential() for details.
s: (numeric)
lower time points.
t: (numeric)
higher time points.

Value

This returns the natural logarithm of the probability of remaining in progression (state 1) between two time points, conditional on being in state 1 at the lower time point.

Examples

transition <- exponential_transition(h01 = 1.2, h02 = 1.5, h12 = 1.6)
log_p11(transition, 1, 3)
#> [1] -3.2
