Thus, we obtain the joint pdf of W and Z as. In this section we obtain distributional results for the quotient of two independent random variables involving Gauss hypergeometric distribution.

## Distribución hipergeométrica

To find the marginal pdf of Zwe integrate 26 with respect to x 2 to get. The Appell’s first hypergeometric function F 1 is defined by. Bivariate distributions based on the generalized three-parameter beta distribution.

Sums, products and ratios of generalized beta variables.

First, we give the following lemma useful in deriving these entropies. It is straightforward to show that. Fader and Bruce G. The CDF of X is evaluated as. The Gauss hypergeometric distribution has also been used by Dauxois 9.

Using the independence, the joint pdf of X 1 and X 2 is given by. The joint pdf of X 1 and X 2 is given by To obtain 19we use 7 to write. 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.

Computationally convenient distributional assumptions for common-value auctions. The generalized beta and F -distributions in statistical modelling.

## Distribuciones estadísticas

Prior assessments for predictions in queues. The beta distribution sometimes does not provide suficient flexibility for a prior for probability of success in a binomial distribution. Several univariate and matrix variate generalizations distribufion this distribution are given in Gordy 1. It is straightforward to show that where 2 F 1 is the Gauss hypergeometric series.

### Product and Quotient of Independent Gauss Hypergeometric Variables

In this article, we derive distributions of the product and the ratio of two independent random variables when at least one of them is Gauss hypergeometric. To obtain 19we use 7 to write and proceed similarly.

Nagar and Erika Alejandra Rada-Mora. Moreover, the cumulative distribution function CDF can be derived in terms of special functions as shown in the following theorem. Sarabia and Castillo For further results and properties, the hipefgeometrica is referred to Aryal and Nadarajah These densities have been expressed in terms of Appell’s first hypergeometric function F 1.

Beta type 3 distribution and its multivariate generalization. Several properties and special cases of this distribution are given in Johnson, Kotz and Balakrishnan 3, p. Chen and Novic In the following theorem, we consider the case where both the random variables are distribkcion as Gauss hypergeometric. Services on Demand Article. The beta distribution is very versatile and a variety of uncertainties can be usefully modeled by it.

Distributions of the product and the quotient of independent Kummer-beta variables. The k -th moment of the variable X having Gauss hypergeometric distribution, obtained in Armero and Bayarri 6.
