The Appell’s first hypergeometric function F 1 is defined by. In this article, we have derived the probability density functions of the hipergemoetrica and the quotient of two independent random variables having Gauss hypergeometric distribution.

Nagar and Erika Alejandra Rada-Mora. Make your selections below, then copy and paste the code below into your HTML source.

Many of disfribucion finite range distributions encountered in practice can easily be transformed into the standard beta distribution. To find the marginal pdf of Zwe integrate 26 with respect to x 2 to get. Bayesian inference for linear growth birth and death processes. Services on Demand Article. Moreover, the cumulative distribution function CDF can be derived in terms of special functions as shown in the following theorem. The above distribution was suggested by Armero and Bayarri 6.

Several properties and special cases of this distribution are given in Johnson, Kotz and Balakrishnan 3, p. Thus, we obtain the joint pdf of W and Z as. On the next page click the “Add” button.

Bayesian analysis for binomial models with generalized beta prior distributions. Finally, integrating w using distrivucion and substituting for K 2 in 28we obtain the desired result. A generalization of the beta distribution with applications. Finally, using Lemma 2. This distribution was defined and used by Libby and Novic Nagar 1 and Danilo Bedoya Valencia 2.


To obtain 19we use 7 to write and proceed similarly.

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

A natural univariate generalization of the beta distribution is the Gauss hypergeometric distribution defined by Armero and Bayarri Appell’s first hypergeometric function, beta distribution, Gauss hypergeometric distribution, quotient, transformation. The graph of the Gauss hypergeometric density for different values of the parameters is shown in the Figure 1.

First, we give the following lemma useful in deriving these entropies. Computationally convenient distributional assumptions for common-value auctions. To include the widget in a wiki page, paste the code below into the page source.

Bivariate distributions based on the generalized three-parameter beta distribution. The beta distribution is very versatile and a variety of uncertainties can be usefully modeled by it. For details see Nadarajah and Zografos For properties and further results of these function the reader is referred to Srivastava and Karlsson Send feedback Visit Wolfram Alpha.

To obtain 19we use 7 to write. It is straightforward to show that where 2 F 1 is the Gauss hypergeometric series. Since X 1 and X 2 are independent, their joint pdf is given by.
