rew: Pseudo-Random Numbers - Exponentiated Weibull

Description

Generates pseudorandom numbers from Exponentiated Weibull Distribution.

Usage

rew(n, beta, c, a)

Arguments

n

Amount of generated numbers.

beta

Scale parameter of the Weibull distribution exponentiated

c

Shape parameter Exponentiated Weibull distribution.

a

Shape parameter exponentiated Weibull distribution.

Details

The exponentiated Weibull family of probability distributions was introduced by Mudholkar and Srivastava (1993) as an extension of the Weibull family obtained by adding a second shape parameter. The function is defined in positive real, ie $x>0$. $$G(x, \beta, c, a) = (1 - e^{-(\beta*x)^c})^{a},$$ wherein $\beta>0$, $c>0$ and $a>0$.
