Expectation Propagation for Poisson Data [PDF]

open access: yes, 2019
The Poisson distribution arises naturally when dealing with data involving counts, and it has found many applications in inverse problems and imaging. In this work, we develop an approximate Bayesian inference technique based on expectation propagation ...

A Berry-Esseen theorem for Pitman's $\alpha$-diversity

open access: yes, 2020
This paper is concerned with the study of the random variable $K_n$ denoting the number of distinct elements in a random sample $(X_1, \dots, X_n)$ of exchangeable random variables driven by the two parameter Poisson-Dirichlet distribution, $PD(\alpha ...

Higher order Hamiltonian fluid reduction of Vlasov equation [PDF]

open access: yes, 2014
From the Hamiltonian structure of the Vlasov equation, we build a Hamiltonian model for the first three moments of the Vlasov distribution function, namely, the density, the momentum density and the specific internal energy. We derive the Poisson bracket

On Zero Truncated Poisson- Muth Distribution [PDF]

open access: yesMaǧallaẗ Al-Buḥūṯ Al-Mālīyyaẗ wa Al-Tiğāriyyaẗ
This paper introduces a novel statistical distribution, the Zero-Truncated Poisson Muth (ZTPM) Distribution, which is particularly useful for analyzing datasets that exclude zero values.

INVESTIGATING POPULATION BALANCE IN THE STATE OF GEORGIA USING SPATIAL CLUSTERING [PDF]

open access: yesریاضی و جامعه
Identification of population ratio disruption in the population structure is one of the challenges that every country faces. Population aging is a kind of demographic abnormality that lack of attention causes population problems.

The Poisson–Lindley Distribution: Some Characteristics, with Its Application to SPC

open access: yesMathematics, 2023
Statistical process control (SPC) is a significant method to monitor processes and ensure quality. Control charts are the most important tools in SPC.

Critical Quantum Chaos in 2D Disordered Systems with Spin-Orbit Coupling

open access: yes, 1999
We examine the validity of the recently proposed semi-Poisson level spacing distribution function P(S), which characterizes `critical quantum chaos', in 2D disordered systems with spin-orbit coupling.

Lensing-Induced Structure of Submillimeter Sources: Implications for the Microwave Background [PDF]

open access: yes, 1999
We consider the effect of lensing by galaxy clusters on the angular distribution of submillimeter wavelength objects. While lensing does not change the total flux and number counts of submillimeter sources, it can affect the number counts and fluxes of ...

A new method for obtaining sharp compound Poisson approximation error estimates for sums of locally dependent random variables

open access: yes, 2010
Let $X_1,X_2,...,X_n$ be a sequence of independent or locally dependent random variables taking values in $\mathbb{Z}_+$. In this paper, we derive sharp bounds, via a new probabilistic method, for the total variation distance between the distribution of ...

Generalized Linear Models in Vehicle Insurance

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
Actuaries in insurance companies try to find the best model for an estimation of insurance premium. It depends on many risk factors, e.g. the car characteristics and the profile of the driver.
