Funciones Beta y Gama Generalizadas Extendidas y sus Aplicaciones

In this article, we define and study generalized forms of extended matrix variate gamma and beta functions. By using a number of results from matrix algebra, special functions of matrix arguments and zonal polynomials we derive a number of properties of these newly defined functions. We also give some applications of these functions to statistical distribution theory.En este artículo definimos y estudiamos formas generalizadas de las funciones gama y beta matriz variadas extendidas.

Distribution of the product of determinants of noncentral bimatrix beta variates

The product moments of existing and new noncentral bimatrix variate beta distributions with bounded domain are derived. From these, exact expressions for the distributions of statistics are obtained by using the Mellin transform. These distributions add value to multivariate statistical analysis with specific reference to factors of Wilks’ statistics and the product of generalized statistics.http://www.elsevier.com/locate/jmvanf201
