pexeest {RPEXE.RPEXT}

RPEXE estimate given change-points

Description

This function estimates the survival probability at tx when a piecewise exponential distribution is fitted to (times,cens) cens = 0 for censored, cens = 1 for uncensored. the change point is tchange and lamest is the estimated parameters

Usage

pexeest(times, cens, tchange, tx)

Arguments

times

All the event/censoring times used to fit the model

cens

censoring status used to fit the model

tchange

Change-points

tx

Time points to estimate the survival probability

Value

quan survival probability lamest Lambda estimates for time periods divided by the change-points

Examples

data(pexeest_times_censoring)
data(t100)
times = pexeest_times_censoring[,1]
cens = pexeest_times_censoring[,2]
pexeest(times, cens, 28.03014, t100)
