Some results envolving the concepts of moment generating function and affinity between distribution functions. Extension for r k-dimensional normal distribution functions [PDF]

open access: yes, 1999
We present a function ρ (F1, F2, t) which contains Matusita's affinity and expresses the affinity between moment generating functions. An interesting results is expressed through decomposition of this affinity ρ (F1, F2, t) when the functions considered ...

Partial Distance Correlation with Methods for Dissimilarities

open access: yes, 2014
Distance covariance and distance correlation are scalar coefficients that characterize independence of random vectors in arbitrary dimension. Properties, extensions, and applications of distance correlation have been discussed in the recent literature ...

Detecting independence of random vectors: generalized distance covariance and Gaussian covariance

open access: yes, 2018
Distance covariance is a quantity to measure the dependence of two random vectors. We show that the original concept introduced and developed by Sz\'{e}kely, Rizzo and Bakirov can be embedded into a more general framework based on symmetric L\'{e}vy ...

Remarks and Open Problems in the Area of the FKG Inequality [PDF]

open access: yes, 1984
The FKG inequality is an effective device when the requisite assumptions can be verified. Sometimes these have to be approached circuitously. This is discussed with reference to past uses and suggestions for work on the range of applicability.

Another generalization of the bivariate FGM distribution with two-dimensional extensions [PDF]

open access: yes, 2012
The Farlie–Gumbel–Morgenstern family of bivariate distributions with given marginals is frequently used in theory and applications and has been generalized in many ways.

A measure of mutual complete dependence [PDF]

open access: yes, 2007
Two random variables X and Y are mutually completely dependent (m.c.d.) if there is a measurable bijection f with P(Y = f(X)) = 1. For continuous X and Y , a natural approach to constructing a measure of dependence is via the distance between the ...

Archimedean Copulae and Positive Dependence. [PDF]

open access: yes
In the first part of the paper we consider positive dependence properties of Archimedean copulae. Especially we characterize the Archimedean copulae that are multivariate totally positive of order 2 (MTP2) and conditionally increasing in sequence. In the

Negative dependence and the geometry of polynomials

open access: yes, 2007
We introduce the class of {\em strongly Rayleigh} probability measures by means of geometric properties of their generating polynomials that amount to the stability of the latter.

Testing conditional independence using maximal nonlinear conditional correlation

open access: yes, 2010
In this paper, the maximal nonlinear conditional correlation of two random vectors $X$ and $Y$ given another random vector $Z$, denoted by $\rho_1(X,Y|Z)$, is defined as a measure of conditional association, which satisfies certain desirable properties ...

Zonoids, Linear Dependence, and Size-Biased Distributions on the Simplex. [PDF]

open access: yes
The zonoid of a d-dimensional random vector is used as a tool for measuring linear dependence among its components. A preorder of linear dependence is defined through inclusion of the zonoids.
