The Beta Exponentiated Gumbel Distribution
We introduce a new five-parameter distribution called the beta exponentiated Gumbel (BEG) distribution that includes the beta Gumbel, exponentiated Gumbel and Gumbel distribution. Expressions for the distribution function, density function and rth moment of the new distribution and order statistics are obtained. We discuss estimation of the parameters by maximum liklelihood ...
متن کاملOn the Distribution of the Product and Ratio of Independent Generalized Gamma-Ratio Random Variables
Using a decomposition of the characteristic function of the logarithm of the product of independent generalized gamma-ratio random variables (r.v.’s), we obtain explicit expressions for both the probability density and cumulative distribution functions of the product of independent r.v.’s with generalized F or generalized gamma-ratio distributions in the form of particular mixtures of generaliz...
متن کاملEXTENSION OF k-GAMMA, k-BETA FUNCTIONS AND k-BETA DISTRIBUTION
In this present paper, the main aim of the authors are to present extended k-gamma, k-beta functions and extended k-beta distribution where k > 0. These newly defined functions are the generalized forms of the extended gamma, beta functions and extended beta distribution. Also, we further generalize the said functions and some of their properties.
متن کاملF/D ratio in hyperon beta decays and the spin distribution in the nucleon.
It is shown that hyperon beta decay data can be well accommodated within the framework of Cabbibo’s SU(3) symmetric description if one allows for a small SU(3) symmetry breaking proportional to the mass difference between strange and nonstrange quarks. The F/D ratio does not depend sensitively on the exact form of the symmetry-breaking, and the best fits are close to the value previously used i...
متن کاملExact Distribution of the Ratio of Gamma and Rayleigh Random Variables
The distributions of the ratio of two independent random variables arise in many applied problems and have been extensively studied by many researchers. This article derives the distributions of the ratio Z= Y X , when X and Y are gamma and Rayleigh random variables respectively and are distributed independently of each other. The associated pdf, cdf, and moments have been given in terms of dif...
