Antisymmetry of the Stochastical Order on all Ordered Topological Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2019
In this short note, we prove that the stochastic order of Radon probability measures on any ordered topological space is antisymmetric. This has been known before in various special cases. We give a simple and elementary proof of the general result.

Behavior of the empirical Wasserstein distance in R^d under moment conditions

open access: yes, 2019
International audienceWe establish some deviation inequalities, moment bounds and almost sure results for the Wasserstein distance of order p ∈ [1, ∞) between the empirical measure of independent and identically distributed R d-valued random variables ...

Dependence properties of bivariate copula families

open access: yesDependence Modeling
Motivated by recently investigated results on dependence measures and robust risk models, this article provides an overview of dependence properties of many well known bivariate copula families, where the focus is on the Schur order for conditional ...

Bernstein’s inequality with a proper cover and upper bound of portfolio VaR and TVaR

open access: yesDependence Modeling
This study develops a concentration inequality for random variables that satisfy Bernstein’s condition when an appropriate cover is present. This inequality generalizes standard concentration results for common distributions, including Gamma, Exponential,

A probabilistic inequality related to negative definite functions

open access: yes, 2020
. We prove that for any pair of i.i.d. random vectors , in ℝ and any real-valued continuous negative definite function : ℝ → ℝ the inequality ( − ) ⩽ ( + ). holds. In particular, for ∈ (0, 2] and the Euclidean norm ∥ ⋅ ∥2 one has The latter inequality is

A Note on the Portfolio Selection Problem

open access: yes, 2005
In this note we provide new results of interest in the portfolio choice problem when the risky opportunities are correlated: for a general vector (X 1 , X 2 ,..., X n ) of risky opportunities we give new conditions for stochastic comparison among ...

VaR bounds in models with partial dependence information on subgroups

open access: yesDependence Modeling, 2017
We derive improved estimates for the model risk of risk portfolios when additional to the marginals some partial dependence information is available.We consider models which are split into k subgroups and consider various classes of dependence ...
