imakeham: Makeham integrated hazard rate function

Description

Computes the integrated hazard rate function of the Makeham distribution

Usage

imakeham(x, t = 1, alpha = 1, beta = 1, epsilon = 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

alpha

the value of alpha parameter, must be positive

epsilon

the value of epsilon parameter, must be positive

beta

the value of beta parameter, must be positive

Value

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