Quantitative de Jong theorems in any dimension [PDF]

open access: yes, 2016
We develop a new quantitative approach to a multidimensional version of the well-known {\it de Jong's central limit theorem} under optimal conditions, stating that a sequence of Hoeffding degenerate $U$-statistics whose fourth cumulants converge to zero ...

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

open access: yesRisks, 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 ...

Application of a Vine Copula for Multi-Line Insurance Reserving

open access: yesRisks, 2020
This article introduces a novel use of the vine copula which captures dependence among multi-line claim triangles, especially when an insurance portfolio consists of more than two lines of business. First, we suggest a way to choose an optimal joint loss

On U-Statistics and Compressed Sensing II: Non-Asymptotic Worst-Case Analysis [PDF]

open access: yes, 2012
In another related work, U-statistics were used for non-asymptotic "average-case" analysis of random compressed sensing matrices. In this companion paper the same analytical tool is adopted differently - here we perform non-asymptotic "worst-case ...

On asymptotic normality for m-dependent U-statistics

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
Let (Xn) be a sequence of m-dependent random variables, not necessarily equally distributed. We give a Berry-Esseen estimate of the convergence to normality of a suitable normalization of a U-statistic of the (Xn).

An Edgeworth Expansion for $U$-Statistics

open access: yesThe Annals of Statistics, 1980
It is shown that, under some regularity conditions on the kernel, a one-sample $U$-statistic with kernel of degree two admits an asymptotic expansion with remainder term $o(N^{-1})$.

UNSUPERVISED CHANGE DETECTION IN SAR IMAGES USING GAUSSIAN MIXTURE MODELS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
In this paper, we propose a method for unsupervised change detection in Remote Sensing Synthetic Aperture Radar (SAR) images. This method is based on the mixture modelling of the histogram of difference image.

JEL Ratio Test for Independence of Time to Failure and Cause of Failure in Competing Risks Data

open access: yesStatistica
In the present article, we propose a Jackknife empirical likelihood (JEL) ratio test for testing the independence of time to failure and cause of failure in competing risks data. We use the U-statistics theory to derive the JEL ratio test. The asymptotic
