Survival probability function of the piecewise exponential distribution with cured population

Description

Calculate survival probability of the piecewise exponential distribution with cured population

Usage

SP_Chen_piecewise_exponential(par, t, piecewiseSurvivalTime)

Arguments

par

a vector with m+1 elements, where the first element denotes the logistic of the proportion of the cured population, and the rest element denotes the log of the hazard rate in intervals

t

a vector with non-negative elements.

piecewiseSurvivalTime

A vector that specifies the time intervals for the piecewise exponential survival distribution. Must start with 0, e.g., c(0, 60) breaks the time axis into 2 event intervals: [0, 60) and [60, Inf). By default, it is set to 0.

Value

Survival probability of the piecewise-exponential distribution with cured population given parameters par at times t.
