Distorted Copulas: Constructions and Tail Dependence [PDF]

, 2010
Given a copula C, we examine under which conditions on an order isomorphism ψ of [0, 1] the distortion C ψ: [0, 1]2 → [0, 1], C ψ(x, y) = ψ{C[ψ−1(x), ψ−1(y)]} is again a copula.

On the inclusion probabilities in some unequal probability sampling plans without replacement

, 2012
Comparison results are obtained for the inclusion probabilities in some unequal probability sampling plans without replacement. For either successive sampling or H\'{a}jek's rejective sampling, the larger the sample size, the more uniform the inclusion ...

Ordinal Welfare Comparisons with Multiple Discrete Indicators: A First Order Dominance Approach and Application to Child Poverty [PDF]

We develop an ordinal method for making welfare comparisons between populations with multidimensional discrete well-being indicators observed at the micro level.

The economics of insurance: a review and some recent developments. [PDF]

The present paper is devoted to different methods of choice under risk in an actuarial setting. The classical expected utility theory is first presented, and its drawbacks are underlined.

Static assignment of complex stochastic tasks using stochastic majorization [PDF]

We consider the problem of statically assigning many tasks to a (smaller) system of homogeneous processors, where a task's structure is modeled as a branching process, and all tasks are assumed to have identical behavior.

Sifting through the noise: Universal first-order methods for stochastic variational inequalities

, 2021
We examine a flexible algorithmic framework for solving monotone variational inequalities in the presence of randomness and uncertainty. The proposed template encompasses a wide range of popular first-order methods, including dual averaging, dual extrapolation and optimistic gradient algorithms – both adaptive and non-adaptive. Our first result is that

Stochastic order inequalities for systems with standby units and parallel-series configurations

Journal of Inequalities and Applications
Abstract In this paper, we first consider stochastic orderings of lifetimes of series and parallel systems with cold standby units. The strategy is to find out whether the reliability of a series or parallel system improves when standby units are installed on the components or on the subsystem.

Copula-based orderings of multivariate dependence [PDF]

In this paper I investigate the problem of defining a multivariate dependence ordering. First, I provide a characterization of the concordance dependence ordering between multivariate random vectors with fixed margins.

Stochastic inequalities involving past extropy of order statistics and past extropy of record values

AIMS Mathematics
<abstract><p>Recently, extropy has emerged as an alternative measure of uncertainty instead of entropy. When it comes to quantifying uncertainty regarding the remaining lifetime of a component, entropy has proven to be less effective. Therefore, the concept of residual entropy was introduced to address this limitation.
