A Generalization of the Hypergeometric Distribution

open access: diamondSultan Qaboos University Journal for Science, 2000
In this paper we introduce a modification of the hypergeometric distribution that caters for the case when the sampling scheme favours the inclusion of units of one of the two types involved, as opposed to the hypergeometric distribution under which all ...

The Confluent Hypergeometric Beta Distribution [PDF]

open access: goldMathematics, 2023
The confluent hypergeometric beta distribution due to Gordy has been known since the 1990s, but not much of is known in terms of its mathematical properties.

A-hypergeometric distributions and Newton polytopes [PDF]

open access: greenAdvances in Applied Mathematics, 2018
We give a bijection between a quotient space of the parameters and the space of moments for any $A$-hypergeometric distribution. An algorithmic method to compute the inverse image of the map is proposed utilizing the holonomic gradient method and an asymptotic equivalence of the map and the iterative proportional scaling.

On hypergeometric generalized negative binomial distribution [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
It is shown that the hypergeometric generalized negative binomial distribution has moments of all positive orders, is overdispersed, skewed to the right, and leptokurtic.

A Conway–Maxwell–Poisson Type Generalization of Hypergeometric Distribution

open access: yesMathematics, 2023
The hypergeometric distribution has gained its importance in practice as it pertains to sampling without replacement from a finite population. It has been used to estimate the population size of rare species in ecology, discrete failure rate in ...

ON A NEW GENERALIZED BETA FUNCTION DEFINED BY THE GENERALIZED WRIGHT FUNCTION AND ITS APPLICATIONS

open access: yesMalaysian Journal of Computing, 2021
Various extensions of classical gamma, beta, Gauss hypergeometric and confluent hypergeometric functions have been proposed recently by many researchers. In this paper, further generalized extended beta function with some of its properties like summation
