Elementary asymptotics for the Stirling numbers of the second kind: The central range

Hsien-Kuei Hwang, Chong-Yi Li, Vytas Zacharovas

We derive the local and central limit theorems for the Stirling numbers of the second kind by elementary means, obtaining as corollaries effective asymptotic estimates for the Bell…

An Elementary Approach to Depoissonization

Vytas Zacharovas

We study depoissonization for sequences with entire exponential generating functions. We establish explicit finite-order remainder bounds for Poisson--Charlier approximations, cont…

Convergence in Distance to the Normal Distribution for Sums of Independent Random Variables

Vytas Zacharovas

Suppose independent random variables have zero mean and equal variance. We prove that if the average of distances between these variables and the n…

Poisson approximation in distance by Chen-Stein approach

Vytas Zacharovas

The main purpose of the paper is to investigate the possibility of applying Chen-Stein approach to estimate the distance between Poisson distribution and a sum of independent…

Inter-state switching in stochastic gene expression: Exact solution, an adiabatic limit and oscillations in molecular distributions

K. G. Petrosyan

We consider the stochastic gene expression process with inter-state flip-flops. An exact steady-state solution to the master equation is calculated. One of the main goals in this p…

The estimate of distance between binomial and generalized binomial distributions

Vytas Zacharovas

We obtain the estimate of difference between binomial and generalized binomial distributions in metric and in several other related metrics
