Development of Rayleigh-Exponentiated Odd Generalized-Weibull Distribution with Properties
Keywords:
REOGWD, Exponentiated distribution, Maximum likelihood estimation, Hazard function, Survival functionAbstract
We propose a new family of distributions called the Rayleigh-Exponentiated odd Generalized-Weibull Distribution with two positive parameters, which generalizes the Cordeiro and de Castro's family. Some special distributions in the new class are discussed. We derive the validity and some mathematical properties of the proposed distribution including explicit expressions for the quantile function, ordinary moments, Moment generating function, hazard and Survival function. The method of maximum likelihood is used to estimation of REOG-Weibull distributions. These functions are illustrated with graphs, since REOGWD was evident through graphics.
