Symmetry and dependence properties within a semiparametric family of bivariate copulas [PDF]

open access: yes, 2002
International audienceIn this paper, we study a semiparametric family of bivariate copulas. The family is generated by an univariate function, determining the symmetry (radial symmetry, joint symmetry) and dependence property (quadrant dependence, total ...

Technical and allocative inefficiency in production systems: a vine copula approach

open access: yesDependence Modeling, 2022
Modeling the error terms in stochastic frontier models of production systems requires multivariate distributions with certain characteristics. We argue that canonical vine copulas offer a natural way to model the pairwise dependence between the two main ...

Successive normalization of rectangular arrays

open access: yes, 2013
Standard statistical techniques often require transforming data to have mean $0$ and standard deviation $1$. Typically, this process of "standardization" or "normalization" is applied across subjects when each subject produces a single number.

An Alternative Type II Claims Pareto Model for Reliability and Bimodal Risk Analysis: Copulas, Properties, Mathematical Modeling, and Actuarial Case Study

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
This article aims to present a new type‐II claims Pareto extension for statistical reliability and actuarial analysis. The new probabilistic density can be simplified in terms of the baseline densities. Some new bivariate types were developed under some copula approaches.

A sharp inequality for Kendall’s τ and Spearman’s ρ of Extreme-Value Copulas

open access: yesDependence Modeling, 2018
We derive a new (lower) inequality between Kendall’s τ and Spearman’s ρ for two-dimensional Extreme-Value Copulas, show that this inequality is sharp in each point and conclude that the comonotonic and the product copula are the only Extreme-Value ...

Test of bivariate independence based on angular probability integral transform with emphasis on circular-circular and circular-linear data

open access: yesDependence Modeling, 2023
The probability integral transform of a continuous random variable XX with distribution function FX{F}_{X} is a uniformly distributed random variable U=FX(X)U={F}_{X}\left(X). We define the angular probability integral transform (APIT) as θU=2πU=2πFX(X){\

Transformation of a copula using the associated co-copula

open access: yesDependence Modeling, 2018
We investigate the properties of a new transformation of copulas based on the co-copula and an univariate function. It is shown that several families in the copula literature can be interpreted as particular outputs of this transformation.
