qew: Exponentiated Weibull quantile function

Description

Computes the quantile function of the exponentiated Weibull distribution

Usage

qew(x, u = 0.5, alpha = 1, c = 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

alpha

the value of alpha parameter, must be positive

lambda

the value of lambda parameter, must be positive

c

the value of c parameter, must be positive

Value

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