Randomly Stopped Sums, Minima and Maxima for Heavy-Tailed and Light-Tailed Distributions

open access: yesAxioms
This paper investigates the randomly stopped sums, minima and maxima of heavy- and light-tailed random variables. The conditions on the primary random variables, which are independent but generally not identically distributed, and counting random ...

Asymptotic Dependence for Light-Tailed Homothetic Densities [PDF]

open access: yesAdvances in Applied Probability, 2012
Dependence between coordinate extremes is a key factor in any multivariate risk assessment. Hence, it is of interest to know whether the components of a given multivariate random vector exhibit asymptotic independence or asymptotic dependence. In the latter case the structure of the asymptotic dependence has to be clarified. In the multivariate setting

Tail asymptotics of light-tailed Weibull-like sums [PDF]

open access: yesProbability and Mathematical Statistics, 2018
TAIL ASYMPTOTICS OF LIGHT-TAILED WEIBULL-LIKE SUMSWe consider sums of n i.i.d. random variables with tailsclose to e xp{−x} for some > 1. Asymptotics developed by Rootzén 1987 and Balkema, Klüppelberg, and Resnick 1993 are discussed from the point of view of tails rather than of densities, using a some what differentangle, and supplemented with ...

Light tails and the Hermitian dual polar graphs [PDF]

open access: yesDesigns, Codes and Cryptography, 2016
Juri i et al. conjectured that if a distance-regular graph $ $ with diameter $D$ at least three has a light tail, then one of the following holds: 1.$a_1 =0$; 2.$ $ is an antipodal cover of diameter three; 3.$ $ is tight; 4.$ $ is the halved $2D+1$-cube; 5.$ $ is a Hermitian dual polar graph $^2A_{2D-1}(r)$ where $r$ is a prime power.

25 years of light-induced petrel groundings in Reunion Island: Retrospective analysis and predicted trends

open access: yesGlobal Ecology and Conservation, 2022
Artificial lights are known to induce mass mortality of petrels. This study analyzes this phenomenon in Reunion Island, where four species are impacted: the endemic Barau’s petrel (Pterodroma baraui) and Mascarene petrel (Pseudobulweria aterrima), the ...

On perpetuities with light tails [PDF]

open access: yesAdvances in Applied Probability, 2018
AbstractIn this paper we consider the asymptotics of logarithmic tails of a perpetuityR=D∑j=1∞Qj∏k=1j-1Mk, where (Mn,Qn)n=1∞are independent and identically distributed copies of (M,Q), for the case when ℙ(M∈[0,1))=1 andQhas all exponential moments. IfMandQare independent, under regular variation assumptions, we find the precise asymptotics of -logℙ(R ...

Asymptotics for the Solutions to Defective Renewal Equations

open access: yesAbstract and Applied Analysis, 2014
This paper investigates the defective renewal equations under the nonconvolution equivalent distribution class. The asymptotics of the solution to the defective renewal equations have been given for the heavy-tailed and light-tailed cases, respectively.

Which Robust Regression Technique Is Appropriate Under Violated Assumptions? A Simulation Study

open access: yesMethodology, 2023
Ordinary least squares (OLS) regression is widely employed for statistical prediction and theoretical explanation in psychology studies. However, OLS regression has a critical drawback: it becomes less accurate in the presence of outliers and non-random ...
