Equations displayed with MathJax. A comparison of the expohentiated gamma and exponentiated Weibull distributions. OSA will be closed for the holidays from 21 December 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.

The Exponentiated 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. The cumulative distribution function for the exponentiated Weibull distribution is. Privacy Terms of Use. 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.

Degenerate Dirac delta function Singular Cantor. Continuous distributions Survival analysis.

Mudholkar and Hutson applied the exponentiated Weibull distribution to extreme value data. 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 moderate turbulence conditions, as well as for point-like apertures.

Woo studied the EW distribution and compared it with the two-parameter Weibull and gamma distributions with respect to failure rate. Abstract 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.

A similar distribution was introduced in by Zacks, called a Weibull-exponential distribution Zacks This website uses cookies to deliver some of our products and services as well as for analytics and to provide you a more personalized experience.

The Exponentiated Weibull distribution is a generalisation of the Weibull distribution which is obtained by exponentiating the Weibull distribtuion distribution function. 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.
