Approximation of Zero-Inflated Poisson Credibility Premium via Variational Bayes Approach

Risks, 2022
While both zero-inflation and the unobserved heterogeneity in risks are prevalent issues in modeling insurance claim counts, determination of Bayesian credibility premium of the claim counts with these features are often demanding due to high ...

Compound Poisson approximation [PDF]

, 2022
We overview the results on the topic of compound Poisson approximation to the distribution of a sum Sn=X1+⋯+Xn of (possibly dependent) random variables.

On lower bounds for Poisson approximation to 2-runs statistic

Lietuvos Matematikos Rinkinys, 2010
Two-runs statistic is approximated by various compound Poisson distributions and second order asymptotic expansions. Estimates of lower bounds are obtained for the uniform Kolmogorov and local metrics.

Effect of variable relative permittivity on the thermodynamics of asymmetric valency aqueous salts

Condensed Matter Physics
Experimentally determined empirical formulae for the concentration dependent relative permittivity of aqueous solutions of MgCl2 and NiCl2 are utilized to calculate the osmotic coefficient and the mean activity coefficient of these salts for a range of ...

Approximation of the classes $W^{r}_{\beta,\infty}$ by three-harmonic Poisson integrals

Karpatsʹkì Matematičnì Publìkacìï, 2019
In the paper, we solve one extremal problem of the theory of approximation of functional classes by linear methods. Namely, questions are investigated concerning the approximation of classes of differentiable functions by $\lambda$-methods of summation ...

A quadratic Poisson Gel'fand-Kirillov problem in prime characteristic [PDF]

, 2015
The quadratic Poisson Gel’fand-Kirillov problem asks whether the field of fractions of a Poisson algebra is Poisson birationally equivalent to a Poisson affine space, i.e. to a polyno-mial algebra K[X1,..., Xn] with Poisson bracket defined by {Xi, Xj} =

ASYMPTOTIC PROPERTIES OF THE IMPULSE PERTURBATION PROCESS UNDER THE POISSON APPROXIMATION CONDITIONS WITH POINT OF EQUILIBRIUM QUALITY CRITERION

Міжнародний науково-технічний журнал "Проблеми керування та інформатики", 2020
For a system of stochastic differential equations with Markov switchings and impulse perturbation under Poisson approximation scheme and under the conditions of the existence of a single equilibrium point of the quality criterion, the limit generators ...

On the Discovery of Significant Motifs in Genomic Sequences [PDF]

, 2013
In this thesis we study the statistical properties of some families of motifs of the same length. We develop a method for the approximation of the average number of frequent motifs in the family in random texts with independent characters.

Stein's method and Poisson process approximation for a class of Wasserstein metrics

, 2009
Based on Stein\’s method, we derive upper bounds for Poisson process approximation in the L1-Wasserstein metric d (p) 2 , which is based on a slightly adapted Lp-Wasserstein metric between point measures.
