Mudholkar, Srivastava, and Kollia applied the generalized Weibull distribution to model survival data. The following R code contains an implementation of the probability density function, cumulative distribution function, quantile function, random number generation, hazard function, and cumulative hazard function of the Exponentiated Weibull distribution using the commands already implemented in R for the Weibull distribution.

Nowadays, the search for a distribution capable of modeling the probability density function PDF of irradiance data under all conditions of atmospheric turbulence in the presence of aperture averaging still continues. Later, the moments of the EW distribution were derived by Choudhury Here, a family of PDFs alternative to the widely accepted Log-Normal and Gamma-Gamma distributions is proposed to model the PDF of the received optical power in free-space optical communications, namely, the Weibull and the exponentiated Weibull EW distribution.

A similar distribution was introduced in by Zacks, called a Weibull-exponential distribution Zacks The Exponentiated Weibull distribution is a generalisation of the Weibull distribution which is obtained by exponentiating the Weibull cumulative distribution function. In statisticsthe exponentiated Weibull family of probability distributions was introduced by Mudholkar and Srivastava as an extension of the Weibull family obtained by adding a second shape parameter. March 28, Published: The Gamma-Gamma GG model is shown for comparison purposes.

The probability density function and cumulative distribution function of the Exponentiated Weibull distribution are respectively given by: Javier Rubio 27 June March 28, Manuscript Accepted: Express 22 17 Mudholkar and Hutson applied the exponentiated Weibull distribution to extreme value data.

Another very attractive property of these distributions is the simple closed form expression of their respective PDF and cumulative distribution function.

Degenerate Dirac delta function Singular Cantor. Particularly, it is shown how the proposed EW distribution offers an excellent fit to simulation and experimental data under all aperture averaging conditions, under weak and dustribution turbulence conditions, as well as for point-like apertures.
