qgompertz: Gompertz quantile function

Description

Computes the quantile function of the Gompertz distribution

Usage

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

alpha

the value of alpha 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 u
