Dependence properties of bivariate copula families

Dependence 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 ...

On kernel-based estimation of conditional Kendall’s tau: finite-distance bounds and asymptotic behavior

Dependence Modeling, 2019
We study nonparametric estimators of conditional Kendall’s tau, a measure of concordance between two random variables given some covariates. We prove non-asymptotic pointwise and uniform bounds, that hold with high probabilities.

A new machine learning approach based on spatial fuzzy data correlation for recognizing sports activities

Demonstratio Mathematica
Wearable sensors (WS) play a vital role in health assistance to improve the patient monitoring process. However, the existing data collection process faces difficulties in error corrections, rehabilitation, and training validations.

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).

Continuous displacement interpolation between checkerboard copulas

Dependence Modeling
This paper presents a displacement-like interpolation method between any two given checkerboard copulas. This interpolation is close to the geodesic connecting the two checkerboard copulas in the L 2-Wasserstein space, which, however, leaves the copula ...

Dependence modeling in general insurance using local Gaussian correlations and hidden Markov models

Dependence Modeling
This 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 ...
