qchen: Chen quantile function

In ActuDistns: Functions for actuarial scientists

Description

Computes the quantile function of the Chen distribution

Usage

qchen(x, u = 0.5, beta = 1, lambda = 1)

Arguments

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

An object of the same length as x, giving the hazard rate function values computed at x and u

Note

If incorrect values or inconsistent lengths are input for x, u or the model parameters then NaNs will be returned as the output.
