ichen: Chen integrated hazard rate function

Description

Computes the integrated hazard rate function of the Chen distribution

Usage

ichen(x, t = 1, beta = 1, lambda = 1)

Arguments

x

scale or vector of positive values at which the integrated hazard rate function needs to be computed

t

scale or vector of positive values at which the integrated hazard rate function needs to be computed, must be of the same length as x

beta

the value of beta parameter, must be positive

lambda

the value of lambda parameter, must be positive

Value

x, giving the hazard rate function values computed at x and t
