qfrechet: Gumbel II quantile function

Description

Computes the quantile function of the Gumbel II 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

a

the value of a parameter, must be positive

b

the value of b parameter, must be positive

Value

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