The compound Poisson limit ruling periodic extreme behaviour of non-uniformly hyperbolic dynamics [PDF]

open access: yes, 2012
We prove that the distributional limit of the normalised number of returns to small neighbourhoods of periodic points of non-uniformly hyperbolic dynamical systems is compound Poisson.

Measure Concentration for Compound Poisson Distributions

open access: yesElectronic Communications in Probability, 2006
We give a simple development of the concentration properties of compound Poisson measures on the nonnegative integers. A new modification of the Herbst argument is applied to an appropriate modified logarithmic-Sobolev inequality to derive new concentration bounds.

Spatial event cluster detection using an approximate normal distribution

open access: yesInternational Journal of Health Geographics, 2008
Background In geographic surveillance of disease, areas with large numbers of disease cases are to be identified so that investigations of the causes of high disease rates can be pursued.

Zero-Inflated Patent Data Analysis Using Compound Poisson Models

open access: yesApplied Sciences, 2023
A large part of big data consists of text documents such as papers, patents or articles. To analyze text data, we have to preprocess the text documents and build a structured data based on a document-word matrix using various text mining techniques. This

Compound Conway-Maxwell Poisson Gamma Distribution: Properties and Estimation

open access: yesAustrian Journal of Statistics
The distribution of a random sum of random events is called a compound distribution. It involves a counting (discrete) distribution to model the number of occurrences of the random event in a fixed time period and a continuous distribution to model the ...

Poisson-type approximation for sums of 1-dependent indicators

open access: yesLietuvos Matematikos Rinkinys, 2009
The sum of 1-dependent indicators is approximated by compound Poisson type distribution. Estimates are obtained for the uniform Kolmogorov and local metrics.

On the Estimation for Compound Poisson Inarch Processes

open access: yesRevstat Statistical Journal, 2021
Considering the wide class of discrete Compound Poisson INARCH models, introduced in [6], the main goal of this paper is to develop and compare parametric estimation procedures for first-order models, applicable without specifying the conditional ...

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 ...

Compound bi-free Poisson distributions [PDF]

open access: yesInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2019
In this paper, we study compound bi-free Poisson distributions for two-faced families of random variables. We prove a Poisson limit theorem for compound bi-free Poisson distributions. Furthermore, a bi-free infinitely divisible distribution for a two-faced family of self-adjoint random variables can be realized as the limit of a sequence of compound ...
