SOME CONDITION ON A POISSON DISTRIBUTION SERIES TO BE IN SUBCLASSES OF UNIVALENT FUNCTIONS

open access: yes, 2017
In this paper, we obtained some condition on Poisson distribution series and some related series to be in subclasses of analytic function. Also, we investigate some mapping properties for these subclasses. 2010 Mathematics Subject Classification: 30C45.

On the computation of poisson probabilities [PDF]

open access: yes, 2019
The Poisson distribution is a distribution commonly used in statistics. It also plays a central role in the analysis of the transient behaviour of continuous-time Markov chains.

Modelando la distribución del número de co-autores por artículo Modeling the distribution of co-authorships by paper

open access: yesInvestigación Bibliotecológica: Archivonomía, Bibliotecología e Información, 2011
Este artículo explora la modelación del número de autores que colaboran en la publicación de un artículo. Con ese fin se analizaron la distribución geométrica, la distribución Poisson truncada, la distribución Poisson lognormal y la distribución Gauss ...

Overdispersion study of poisson and zero-inflated poisson regression for some characteristics of the data on lamda, n, p

open access: yesIJAIN (International Journal of Advances in Intelligent Informatics), 2016
Poisson distribution is one of discrete distribution that is often used in modeling of rare events. The data obtained in form of counts with non-negative integers. One of analysis that is used in modeling count data is Poisson regression.

On the Distribution of Haloes, Galaxies and Mass

open access: yes, 2002
The stochasticity in the distribution of dark haloes in the cosmic density field is reflected in the distribution function $P_V(N_h|\delta_m)$ which gives the probability of finding $N_h$ haloes in a volume $V$ with mass density contrast $\delta_m$.

An Exact and an Approximation Method to Compute the Degree Distribution of Inhomogeneous Random Graph Using Poisson Binomial Distribution

open access: yesMathematics, 2023
Inhomogeneous random graphs are commonly used models for complex networks where nodes have varying degrees of connectivity. Computing the degree distribution of such networks is a fundamental problem and has important applications in various fields.

Mixed Poisson Distributions

open access: yesInternational Statistical Review, 2007
Summary Mixed Poisson distributions have been used in a wide range of scientific fields for modeling non homogeneous populations. This paper aims at reviewing the existing literature on Poisson mixtures by bringing together a great number of properties, while, at the same time, providing tangential information on general mixtures.

The density ratio of Poisson binomial versus Poisson distributions

open access: yesStatistics & Probability Letters, 2020
Let $b(x)$ be the probability that a sum of independent Bernoulli random variables with parameters $p_1, p_2, p_3, \ldots \in [0,1)$ equals $x$, where $ := p_1 + p_2 + p_3 + \cdots$ is finite. We prove two inequalities for the maximal ratio $b(x)/ _ (x)$, where $ _ $ is the weight function of the Poisson distribution with parameter $ $.

Properties of the zero-and-one inflated Poisson distribution and likelihood-based inference methods

open access: yes, 2016
To model count data with excess zeros and excess ones, in their unpublished manuscript, Melkersson and Olsson (1999) extended the zero-inflated Poisson distribution to a zero-and-one-inflated Poisson (ZOIP) distribution.

Mittag - Leffler function distribution - a new generalization of hyper-Poisson distribution [PDF]

open access: yes, 2014
In this paper a new generalization of the hyper-Poisson distribution is proposed using the Mittag-Leffler function. The hyper-Poisson, displaced Poisson, Poisson and geometric distributions among others are seen as particular cases.
