| SP_Chen_piecewise_exponential {EventPredInCure} | R Documentation |
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.
