The generalized beta and F -distributions in statistical modelling. Make your selections below, then copy and paste the code below into your HTML source. Computationally convenient distributional assumptions for common-value auctions. The following theorem suggests a generalized beta type 2 distribution, from the Gauss hypergeometric distribution. Finally, integrating w using 10 and substituting for K hipergeometfica in 28we obtain the desired result. Enable Javascript to interact with content and submit forms on Wolfram Alpha websites.

Information matrix for beta distributions. Thus, we obtain the joint pdf of W and Z as. Among various properties, the distribution defined by the density 5 can more flexibly account for heavy tails or skewness, and it reduces to the ordinary beta type 1 distribution for certain parameter choices.

Sarabia and Castillo In this section, we give definitions and results that are used in subsequent distribucipn. The CDF of X is evaluated as.

Spanish pdf Article in distribucjon format Article references How to cite this article Automatic translation Send this article by e-mail. Distributions of the product and quotient of independent beta type 3 variables. Properties of multivariate beta distributions.


The graph of the Gauss hypergeometric density for different values of the parameters is shown in the Figure 1.

For properties and further results of these function the reader is referred to Srivastava and Karlsson Now, using the hipergrometrica of the Appell’s first hypergeometric function, we get the desired result. Build a new widget. First, we give the following lemma useful in deriving these entropies. These densities have been expressed in terms of Appell’s first hypergeometric function F 1.

Nagar 1 and Danilo Bedoya Valencia 2. The Gauss hypergeometric distribution has also been used by Dauxois 9. hhipergeometrica

Applied Probability and Statistics. Beta type 3 distribution and its multivariate generalization. Many of the finite range distributions encountered in practice can easily be transformed into the standard beta distribution.

Fader and Bruce G. It is defined by. Distributions of the product and the quotient of independent Kummer-beta variables. Nagar and Erika Alejandra Rada-Mora. Bivariate distributions based on the generalized three-parameter beta distribution. For further results and properties, the reader hiperrgeometrica referred to Aryal and Nadarajah This distribution was defined and used by Libby and Novic 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.
