qpwe: Piecewise exponential distribution: quantile function

In PWEALL: Design and Monitoring of Survival Trials Accounting for Complex Situations

Piecewise exponential distribution: quantile function

Description

This will provide the quantile function of the specified piecewise exponential distribution

Usage

qpwe(p=seq(0,1,by=0.1),rate=c(0,5,0.8),tchange=c(0,3))

Arguments

p	a vector of probabilities
rate	piecewise constant event rate
tchange	time points at which event rate changes. This must be an strictly increasing sequence starting from zero. rate and tchange must have the same length.
