The combinatorial structure of beta negative binomial processes

open access: yes, 2016
We characterize the combinatorial structure of conditionally-i.i.d. sequences of negative binomial processes with a common beta process base measure. In Bayesian nonparametric applications, such processes have served as models for latent multisets of ...

Analysis of generalized negative binomial distributions attached to hyperbolic Landau levels

open access: yes, 2016
To each hyperbolic Landau level of the Poincar\'e disc is attached a generalized negative binomial distribution. In this paper, we compute the moment generating function of this distribution and supply its decomposition as a perturbation of the negative ...

Transform methods for testing the negative binomial hypothesis

open access: yesStatistica, 2007
We employ the empirical probability generating function in constructing a goodness-of-fit test for negative binomial distributions. The proposed tests, which are formed as weighted integrals, are shown to be consistent and their asymptotic null ...

Safety evaluation of urban roundabouts in India: a safety performance function-based approach

open access: yesTraffic Safety Research, 2022
There is a lack of comprehensive research in roundabout safety under non-lane-based traffic conditions, mainly due to the absence of relevant crash data and effective tools for safety evaluation.

ZERO INFLATED NEGATIVE BINOMIAL MODELS IN SMALL AREA ESTIMATION [PDF]

open access: yes, 2008
The problem of over-dispersion in Poisson data is usually solved by introducing prior distributions which lead to negative binomial models. Poisson data sometime is also suffered by excess zero problems, a condition when data contains too many zero or ...

On the forward-backward correlations in a two-stage scenario [PDF]

open access: yes, 2000
It is demonstrated that in a two-stage scenario with elementary Poissonian emitters of particles (colour strings) arbitrarily distributed in their number and average multiplicities, the forward- backward correlations are completely determined by the ...

Football goal distributions and extremal statistics [PDF]

open access: yes, 2002
We analyse the distributions of the number of goals scored by home teams, away teams, and the total scored in the match, in domestic football games from 169 countries between 1999 and 2001. The probability density functions (PDFs) of goals scored are too

A Modified Negative Binomial Distribution: Properties, Overdispersion and Underdispersion

open access: yesJournal of Statistical Theory and Applications (JSTA), 2019
In this paper, we introduce a new and useful discrete distribution (modified negative binomial distribution) and its statistical and probabilistic properties are discussed.

Stochastic Ordering of Exponential Family Distributions and Their Mixtures

open access: yes, 2009
We investigate stochastic comparisons between exponential family distributions and their mixtures with respect to the usual stochastic order, the hazard rate order, the reversed hazard rate order, and the likelihood ratio order.

Calculation of some determinants using the s-shifted factorial [PDF]

open access: yes, 2004
Several determinants with gamma functions as elements are evaluated. This kind of determinants are encountered in the computation of the probability density of the determinant of random matrices. The s-shifted factorial is defined as a generalization for
