Asymptotic formulas for the left truncated moments of sums with consistently varying distributed increments

open access: yesNonlinear Analysis, 2021
In this paper, we consider the sum Snξ = ξ1 + ... + ξn of possibly dependent and nonidentically distributed real-valued random variables ξ1, ... , ξn with consistently varying distributions. By assuming that collection {ξ1, ...

An application of stochastic approximation in simulated method of moments [PDF]

open access: yesMathematics and Modeling in Finance, 2021
Identifying the structures of dependence between financial assets is one of the interesting topics to researchers. However, there are challenges to this purpose. One of them is the modelling of heavy tail distributions.

Heavy-Tailed Diffusion Models

open access: yesarXiv.org
Diffusion models achieve state-of-the-art generation quality across many applications, but their ability to capture rare or extreme events in heavy-tailed distributions remains unclear.

Tail Risk Inference via Expectiles in Heavy-Tailed Time Series [PDF]

open access: yesJournal of Business & Economic Statistics, 2020
Expectiles define the only law-invariant, coherent and elicitable risk measure apart from the expectation. The popularity of expectile-based risk measures is steadily growing and their properties have been studied for independent data, but further ...

On the Heavy-Tail Behavior of the Distributionally Robust Newsvendor [PDF]

open access: yesOperational Research, 2018
Distributionally robust optimization is increasingly becoming a popular methodology to deal with uncertainty in optimization problems. Although the methodology optimizes for the worst-case distribution, a better understanding of the prescriptions from ...

Inferring heavy tails of flood distributions through hydrograph recession analysis [PDF]

open access: yesHydrology and Earth System Sciences, 2023
Floods are often disastrous due to underestimation of the magnitude of rare events. Underestimation commonly happens when the magnitudes of floods follow a heavy-tailed distribution, but this behavior is not recognized and thus neglected for flood hazard

Diffusion Approximation for Fokker Planck with Heavy Tail Equilibria: A Spectral Method in Dimension 1 [PDF]

open access: yesCommunications in Mathematical Physics, 2017
This paper is devoted to the diffusion approximation for the 1-d Fokker Planck equation with a heavy tail equilibria of the form $${(1+v^2)^{-\beta/2}}$$(1+v2)-β/2, in the range $${\beta\in ]1,5[}$$β∈]1,5[.

When Idling is Ideal: Optimizing Tail-Latency for Heavy-Tailed Datacenter Workloads with Perséphone

open access: yesSymposium on Operating Systems Principles, 2021
This paper introduces Perséphone, a kernel-bypass OS scheduler designed to minimize tail latency for applications executing at microsecond-scale and exhibiting wide service time distributions.

Randomly Stopped Sums with Generalized Subexponential Distribution

open access: yesAxioms, 2023
Let {ξ1,ξ2,…} be a sequence of independent possibly differently distributed random variables, defined on a probability space (Ω,F,P) with distribution functions {Fξ1,Fξ2,…}. Let η be a counting random variable independent of sequence {ξ1,ξ2,…}.
