Multivariate Tail Probabilities: Predicting Regional Pertussis Cases in Washington State [PDF]

open access: yesEntropy, 2021
In disease modeling, a key statistical problem is the estimation of lower and upper tail probabilities of health events from given data sets of small size and limited range.

Sample-Path Large Deviations in Credit Risk [PDF]

open access: yesJournal of Applied Mathematics, 2011
The event of large losses plays an important role in credit risk. As these large losses are typically rare, and portfolios usually consist of a large number of positions, large deviation theory is the natural tool to analyze the tail asymptotics of the ...

Tail probabilities for triangular arrays [PDF]

open access: yesJournal of Dynamics & Games, 2014
Di erent discrete time triangular arrays representing a noisy signal of players' activities can lead to the same limiting di usion process yet lead to di erent limit equilibria. Whether the limit equilibria are equilibria of the limiting continuous time

Estimation of Tail Probabilities by Repeated Augmented Reality. [PDF]

open access: yesJ Stat Theory Pract, 2021
Synthetic data, when properly used, can enhance patterns in real data and thus provide insights into different problems. Here, the estimation of tail probabilities of rare events from a moderately large number of observations is considered. The problem is approached by a large number of augmentations or fusions of the real data with computer-generated ...

Enhanced active learning Gaussian process metamodel for estimating the one-sided tail probability of nonlinear structural response [PDF]

open access: yesScientific Reports
The safety operation and maintenance of mega-structures in China are increasingly challenged by rare but high-impact structural failures. To address the difficulty in accurately estimating the low-probability tail of the response distribution, we propose

Tail Probabilities of Noncentral Quadratic Forms

open access: yesAnnals of Statistics, 1975
Let $S(b) = \Sigma r\sigma r^2Xr^2(nr,br^2)$ be a positive linear combination of independent noncentral chi-square random variables. This note derives two representations for the tail probabilities P[S(b) >x], a Taylor series in the noncentrality parameters and a limiting form of this series for large x.

An exact bound for tail probabilities for a class of conditionally symmetric bounded martingales

open access: yesLietuvos Matematikos Rinkinys, 2023
We consider the class, say ℳn,sym, of martingales Mn = X1 + ⋯ + Xn with conditionally symmetric bounded differences Xk such that |Xk | ≤ 1. We find explicitly a solution, say Dn(x), of the variational problem Dn(x) ≝ sup Mn ∈ℳn,sym ℙ {Mn ≥ x}.

Tail probability and divergent series [PDF]

open access: yesJournal of Interdisciplinary Mathematics, 2021
From mostly a measure-theoretic consideration, we show that for every nonnegative, finite, and $L^{1}$ function on a given finite measure space there is some nontrivial sequence of real numbers such that the series, obtained from summing over the term-by-term products of the reals and the summands of any divergent series with positive, vanishing ...

Trivariate copula to design coastal structures [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2021
Some coastal structures must be redesigned in the future due to rising sea levels caused by climate change. The design of structures subjected to the actions of waves requires an accurate estimate of the long return period of such parameters as wave ...

Bounds for Tail Probabilities of the Sample Variance

open access: yesJournal of Inequalities and Applications, 2009
We provide bounds for tail probabilities of the sample variance. The bounds are expressed in terms of Hoeffding functions and are the sharpest known.
