Buy-and-Hold Strategies and Comonotonic Approximations [PDF]

open access: yes, 2013
[cat] En aquest article estudiem estratègies “comprar i mantenir” per a problemes d’optimitzar la riquesa final en un context multi-període. Com que la riquesa final és una suma de variables aleatòries dependents, on cadascuna d’aquestes correspon a una ...

Logical Approximations of Qualitative Probability. [PDF]

open access: yes, 2021
We provide approximations of qualitative probability, that is, comparative structures which are representable by probability measures. We introduce sequences of qualitative belief structures, based on the ideas of Depth-Bounded logics D’Agostino et al ...

Continuum Approximation of Invasion Probabilities [PDF]

open access: yesMultiscale Modeling & Simulation, 2017
Abstract In the last decade there has been growing criticism of the use of Stochastic Differential Equations (SDEs) to approximate discrete state-space, continuous-time Markov chain population models. In particular, several authors have demonstrated the failure of Diffusion Approximation

Approximations of the ruin probability in a discrete time risk model

open access: yesModern Stochastics: Theory and Applications, 2020
Based on a discrete version of the Pollaczeck–Khinchine formula, a general method to calculate the ultimate ruin probability in the Gerber–Dickson risk model is provided when claims follow a negative binomial mixture distribution.

Integral Approximations for Coverage Probability [PDF]

open access: yesIEEE Wireless Communications Letters, 2016
This letter gives approximations to an integral appearing in the formula for downlink coverage probability of a typical user in Poisson point process (PPP) based stochastic geometry frameworks of the form $\int_0^\infty \exp\{ - (Ax + B x^{α/2}) \} \ud x$. Four different approximations are studied.

Asymptotic Diffusion Analysis of Multi-Server Retrial Queue with Hyper-Exponential Service

open access: yesMathematics, 2020
A multi-server retrial queue with a hyper-exponential service time is considered in this paper. The study is performed by the method of asymptotic diffusion analysis under the condition of long delay in orbit.

Approximating the Density of Random Differential Equations with Weak Nonlinearities via Perturbation Techniques

open access: yesMathematics, 2021
We combine the stochastic perturbation method with the maximum entropy principle to construct approximations of the first probability density function of the steady-state solution of a class of nonlinear oscillators subject to small perturbations in the ...

Ruin Probability Approximations in Sparre Andersen Models with Completely Monotone Claims

open access: yesRisks, 2019
We consider the Sparre Andersen risk process with interclaim times that belong to the class of distributions with rational Laplace transform. We construct error bounds for the ruin probability based on the Pollaczek−Khintchine formula, and develop ...
