Fader and Bruce G. In the following theorem, we consider the case where both the random variables are distributed as Gauss hypergeometric.

A mathematical theory of communication. To add a widget to a MediaWiki site, the wiki must have the Widgets Extension installed, as well as the code for the Wolfram Alpha widget. The joint pdf of X 1 and X 2 is given by To obtain 19we use 7 to write.

Distributions of the product and the quotient of independent Kummer-beta variables. To embed a widget hipfrgeometrica your blog’s sidebar, install the Wolfram Alpha Widget Sidebar Pluginand copy and paste the Widget ID below into the “id” field:.

A natural univariate generalization of the beta distribution is the Gauss hypergeometric distribution defined by Armero and Bayarri The Appell’s first hypergeometric function F 1 is defined by.

The integral representation of the Gauss hypergeometric function is given as. To find the marginal pdf of Zwe integrate 26 with respect to x 2 to get. The beta distribution is very versatile and a variety of uncertainties can be usefully modeled by it.

Multivariate generalized beta distributions with applications to utility assessment. The generalized beta and F -distributions in statistical modelling.

Finally, applying 10we obtain the desired distribucoon. Several properties and special cases of this distribution are given in Johnson, Kotz and Balakrishnan 3, p.

Finally, using Lemma 2.

Finally, integrating w using 10 and hjpergeometrica for K 2 in 28we obtain the desired result. Computationally convenient distributional assumptions for common-value auctions. It is defined by. In the context of Bayesian analysis of unreported Poisson count data, while deriving the marginal posterior distribution of the reporting probablity p, Fader and Hardie 8.

This distribution was defined and used by Libby and Novic Enable Javascript to interact with content and submit forms on Wolfram Alpha websites. Using the independence, the joint pdf of X 1 and X 2 is given by. The k -th moment of the variable X having Gauss hypergeometric distribution, obtained in Armero and Bayarri 6. This generalized entropy measure is given by.
