Weighted Entropic Copula from Preliminary Knowledge of Dependence
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018 This paper introduces a weighted entropic copula from preliminary knowledge of dependence. Considering a copula with common distribution we formulate the weighted entropy dependence model (WMEC).

Multivariate data analysis: The French way
, 2008 This paper presents exploratory techniques for multivariate data, many of them well known to French statisticians and ecologists, but few well understood in North American culture.

Distortion Risk Measures and Discrete Risks [PDF]
In this paper we consider the problem of determining approximations for distortion risk measures of sums of non-independent random variables. First, we give an overview of the recent actuarial literature on distortion risk measures and convex bounds for ...

Limit distributions of upper order statistics for families of multivariate distributions [PDF]
, 2018 We consider a portfolio of dependent exchangeable random variables $$X_1, \ldots, X_n$$ , where the dependence structure is generated by a mixture model (Archimedean copulas belong to this class of models). Define the ordered sample $$X_{1,n} \ge X_{2,n}

Measuring and testing dependence by correlation of distances
, 2008 Distance correlation is a new measure of dependence between random vectors. Distance covariance and distance correlation are analogous to product-moment covariance and correlation, but unlike the classical definition of correlation, distance correlation ...

Profile identification via weighted related metric scaling : an application to dependent Spanish children [PDF]
, 2011 AMS subject classification: 62-07, 62-09, 62H20, 62H99, 62P05Disability and dependency (lack of autonomy in performing common everyday actions) affect health status and quality of life, therefore they are significant public health issues.

Dependence modeling in general insurance using local Gaussian correlations and hidden Markov models
Dependence ModelingThis article introduces a hybrid framework that combines local Gaussian correlation (LGC) with hidden Markov models (HMMs) to model dynamic and nonlinear dependencies in general insurance claims, thereby addressing the limitations of static copula ...

On comprehensive families of copulas involving the three basic copulas and transformations thereof
Dependence ModelingComprehensive families of copulas including the three basic copulas (at least as limit cases) are useful tools to model countermonotonicity, independence, and comonotonicity of pairs of random variables on the same probability space. In this contribution,
