On a Method of Introducing Free-Infinitely Divisible Probability Measures

open access: yesDemonstratio Mathematica, 2016
Random integral mappings give isomorphism between the subsemigroups of the classical (I D, *) and the free-infinite divisible (I D, ⊞) probability measures.

Marshall-Olkin Generalized Asymmetric Laplace distributions and processes

open access: yesStatistica, 2013
The Marshall-Olkin Generalised Asymmetric Laplace distribution is introduced and studied. An approximation is made and various properties including self decomposability, geometric infinite divisibility, limit properties etc.are established.

Mathematics and the real world

open access: yesKoers : Bulletin for Christian Scholarship, 2000
In this article the initial discussion of the untenability of the distinction between “pure” and “applied" mathematics is followed by looking at alternative approaches regarding the relationship between mathematics and the “real world” - with ...

Hypergraphs with infinitely many extremal constructions

open access: yesDiscrete Analysis, 2023
Hypergraphs with infinitely many extremal constructions, Discrete Analysis 2023:18, 34 pp. A fundamental result in extremal graph theory, Turán's theorem, states that the maximal number of edges of a graph with $n$ vertices that does not contain a ...

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 ...

Infinite Divisibility and Max-Infinite Divisibility with Random Sample Size

open access: yes, 2003
Continuing the study reported in Satheesh (2001),(math.PR/0304499 dated 01 May 2003) and Satheesh (2002)(math.PR/0305030 dated 02May 2003), here we study generalizations of infinitely divisible (ID) and max-infinitely divisible (MID) laws. We show that these generalizations appear as limits of random sums and random maximums respectively.

Equivalence of Infinitely Divisible Distributions

open access: yesThe Annals of Probability, 1975
If $F$ is an infinitely divisible distribution function without a Gaussian component whose Levy spectral measure $M$ is absolutely continuous and $M(\mathbb{R}^1\backslash\{0\}) = \infty$, then $F$ is shown to have an a.e. positive density over its support; this support of $F$ is always an interval of the form $(-\infty, \infty), (-\infty, a\rbrack$ or

Discrete New Generalized Pareto Distribution

open access: yesStatistica
In this paper we propose a discrete analogue of New Generalized Pareto distribution as a new discrete model using general approach of discretization of continuous distribution. The structural properties of the new distribution are discussed.
