Three classes of decomposable distributions

open access: yesOpen Mathematics, 2020
In this work, we refine the results of Sendov and Shan [New representation theorems for completely monotone and Bernstein functions with convexity properties on their measures, J. Theor. Probab.

The de Finetti structure behind some norm-symmetric multivariate densities with exponential decay

open access: yesDependence Modeling, 2020
We derive a sufficient condition on the symmetric norm ||·|| such that the probability distribution associated with the density function f (x) ∝exp(−λ ||x||) is conditionally independent and identically distributed in the sense of de Finetti’s seminal ...

On fixed points of Poisson shot noise transforms [PDF]

open access: yes, 2002
Distributional fixed points of a Poisson shot noise transform (for nonnegative, nonincreasing response functions bounded by 1) are characterized. The tail behavior of fixed points is described.

Derivation of an integral of Boros and Moll via convolution of Student t-densities [PDF]

open access: yes, 2010
We show that the evaluation of an integral considered by Boros and Moll is a special case of a convolution result about Student t-densities obtained by the authors in ...

New characterizations of completely monotone functions and Bernstein functions, a converse to Hausdorff’s moment characterization theorem

open access: yesArab Journal of Mathematical Sciences, 2019
We give several new characterizations of completely monotone functions and Bernstein functions via two approaches: the first one is driven algebraically via elementary preserving mappings and the second one is developed in terms of the behavior of their ...

Sample correlations of infinite variance time series models: an empirical and theoretical study

open access: yesInternational Journal of Stochastic Analysis, Volume 11, Issue 3, Page 255-282, 1998., 1998
When the elements of a stationary ergodic time series have finite variance the sample correlation function converges (with probability 1) to the theoretical correlation function. What happens in the case where the variance is infinite? In certain cases, the sample correlation function converges in probability to a constant, but not always.

Probability measures on compact groups which have square-integrable densities [PDF]

open access: yes, 2008
We apply Peter–Weyl theory to obtain necessary and sufficient conditions for a probability measure on a compact group to have a square-integrable density.

Weak stability and generalized weak convolution for random vectors and stochastic processes [PDF]

open access: yes, 2006
A random vector ${\bf X}$ is weakly stable iff for all $a,b\in \mathbb{R}$ there exists a random variable $\Theta$ such that $a{\bf X}+b{\bf X}'\stackrel{d}{=}{\bf X}\Theta$.

Quasi-invariance of countable products of Cauchy measures under non-unitary dilations [PDF]

open access: yes, 2018
Consider an infinite sequence (Un)n∈N of independent Cauchy random variables, defined by a sequence (δn)n∈N of location parameters and a sequence (γn)n∈N of scale parameters. Let (Wn)n∈N be another infinite sequence of independent Cauchy random variables

On free stable distributions [PDF]

open access: yes, 2014
We investigate the analytical properties of free stable distributions and discover many connections with the classical stable distributions. Our main results include an explicit formula for the Mellin transform, series representations for the ...
