Sums, products and ratios of generalized beta variables. First, we give the following lemma useful in deriving these entropies.

Information matrix for beta distributions. Bayesian inference for linear growth birth and death processes.

Distribucino further results and properties, the reader is referred to Aryal and Nadarajah 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. To obtain 19we use 7 to write and proceed similarly.


Multivariate generalized beta distributions with applications to utility assessment. Thus, we obtain the joint pdf of W and Z as. It is straightforward to show that.

Sarabia and Castillo The beta distribution is very versatile and a variety of uncertainties can be usefully modeled by it. To find the marginal pdf of Zwe integrate 26 with respect to x 2 to get. The generalized beta and F -distributions in statistical modelling.

Let be a probability space. For properties and further results the reader is referred to Luke On the next page click the “Add” button. Fader and Bruce G. A mathematical theory of communication.


A generalization of the beta distribution with applications. 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. The following theorem suggests a generalized beta type 2 distribution, from the Gauss hypergeometric distribution.
