Two Measures of Dependence [PDF]

open access: yesEntropy, 2019
Two families of dependence measures between random variables are introduced. They are based on the Rényi divergence of order α and the relative

Model Selection Based on Residual Dependence Measure [PDF]

open access: yesIEEE Access, 2023
Choosing the most suitable model from a set of models is crucial. Based on the assumption that the noise and independent variables in the model are independent, the degree of fit of the model was determined by studying the correlation between the ...

A subcopula based dependence measure [PDF]

open access: yesKybernetika, 2017
A dependence measure for arbitrary type pairs of random variables is proposed and analyzed, which in the particular case where both random variables are continuous turns out to be a concordance measure. Also, a sample version of the proposed dependence measure based on the empirical subcopula is provided, along with an R package to perform the ...

Dependence measure for length-biased survival data using copulas [PDF]

open access: yesDependence Modeling, 2019
The linear correlation coefficient of Bravais-Pearson is considered a powerful indicator when the dependency relationship is linear and the error variate is normally distributed.

Continuous dependence results for set-valued measure differential problems [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
We discuss existence and continuous dependence properties of solutions set of measure differential inclusions \begin{equation}\label{(1)} \begin{split} dx(t)& \in G(t, x(t)) d\mu(t),\\ x(0)& = x_0. \end{split} \end{equation} where $G \colon [0,1] \times \

Extending Hilbert–Schmidt Independence Criterion for Testing Conditional Independence

open access: yesEntropy, 2023
The Conditional Independence (CI) test is a fundamental problem in statistics. Many nonparametric CI tests have been developed, but a common challenge exists: the current methods perform poorly with a high-dimensional conditioning set.

Maximal asymmetry of bivariate copulas and consequences to measures of dependence

open access: yesDependence Modeling, 2022
In this article, we focus on copulas underlying maximal non-exchangeable pairs (X,Y)\left(X,Y) of continuous random variables X,YX,Y either in the sense of the uniform metric d∞{d}_{\infty } or the conditioning-based metrics Dp{D}_{p}, and analyze their ...

Ordinal pattern dependence as a multivariate dependence measure [PDF]

open access: yesJournal of Multivariate Analysis, 2021
In this article, we show that the recently introduced ordinal pattern dependence fits into the axiomatic framework of general multivariate dependence measures, i.e., measures of dependence between two multivariate random objects. Furthermore, we consider multivariate generalizations of established univariate dependence measures like Kendall's $τ ...

Searching With Measurement Dependent Noise [PDF]

open access: yesIEEE Transactions on Information Theory, 2014
Consider a target moving at a constant velocity on a unit-circumference circle, starting at an arbitrary location. To acquire the target, any region of the circle can be probed to obtain a noisy measurement of the target's presence, where the noise level increases with the size of the probed region.

A link between Kendall’s τ, the length measure and the surface of bivariate copulas, and a consequence to copulas with self-similar support

open access: yesDependence Modeling, 2023
Working with shuffles, we establish a close link between Kendall’s τ\tau , the so-called length measure, and the surface area of bivariate copulas and derive some consequences.
