Poisson approximation [PDF]

open access: yesProbability Surveys, 2019
We overview results on the topic of Poisson approximation that are missed in existing surveys. The topic of Poisson approximation to the distribution of a sum of integer-valued random variables is presented as well. We do not restrict ourselves to a particular method, and overview the whole range of issues including the general limit theorem, estimates

Poisson Approximation for Dependent Trials

open access: yesAnnals of Probability, 1975
Let $X_1, \cdots, X_n$ be an arbitrary sequence of dependent Bernoulli random variables with $P(X_i = 1) = 1 - P(X_i = 0) = p_i.$ This paper establishes a general method of obtaining and bounding the error in approximating the distribution of $\sum^n_{i=1} X_i$ by the Poisson distribution.

On the Poisson equation and diffusion approximation 3

open access: yesAnnals of Probability, 2005
We study the Poisson equation Lu+f=0 in R^d, where L is the infinitesimal generator of a diffusion process. In this paper, we allow the second-order part of the generator L to be degenerate, provided a local condition of Doeblin type is satisfied, so ...

A Semigroup Approach to Poisson Approximation

open access: yesAnnals of Probability, 1986
Let \(X_ 1,...,X_ n\) be independent Bernoulli r.v.'s with \(p_ j=P(X_ j=1)=1-P(X_ j=0 ...

A General Poisson Approximation Theorem

open access: yesAnnals of Probability, 1975
A sum of nonnegative integer-valued random variables may be treated as a Poisson variable if the summands have sufficiently high probabilities of taking 0 value and sufficiently weak mutual dependence. This paper presents simple exact upper bounds for the error of such an approximation.

On moderate deviations in Poisson approximation [PDF]

open access: yesJournal of Applied Probability, 2020
AbstractIn this paper we first use the distribution of the number of records to demonstrate that the right tail probabilities of counts of rare events are generally better approximated by the right tail probabilities of a Poisson distribution than those of the normal distribution.

Relaxation of monotone coupling conditions: Poisson approximation and beyond [PDF]

open access: yes, 2017
It is well-known that assumptions of monotonicity in size-bias couplings may be used to prove simple, yet powerful, Poisson approximation results. Here we show how these assumptions may be relaxed, establishing explicit Poisson approximation bounds ...

PoisFFT - A Free Parallel Fast Poisson Solver [PDF]

open access: yes, 2014
A fast Poisson solver software package PoisFFT is presented. It is available as a free software licensed under the GNU GPL license version 3. The package uses the fast Fourier transform to directly solve the Poisson equation on a uniform orthogonal grid.

The lower tail: Poisson approximation revisited [PDF]

open access: yes, 2014
The well-known "Janson's inequality" gives Poisson-like upper bounds for the lower tail probability \Pr(X \le (1-\eps)\E X) when X is the sum of dependent indicator random variables of a special form.
