Dependence uncertainty bounds for the energy score and the multivariate Gini mean difference

open access: yesDependence Modeling, 2020
The energy distance and energy scores became important tools in multivariate statistics and multivariate probabilistic forecasting in recent years. They are both based on the expected distance of two independent samples. In this paper we study dependence

A strong deviation theorem and its application to herding effect

open access: yesResults in Applied Mathematics, 2020
Wang and Yang (2011) studied the strong deviation theorems of the n-th order identical distribution (for short i.d.) random sequences. In the present paper we arrive at the strong deviation theorems for the moving averages of the third order non ...

Bounding the maximum likelihood degree [PDF]

open access: yes, 2015
Maximum likelihood estimation is a fundamental computational problem in statistics. In this note, we give a bound for the maximum likelihood degree of algebraic statistical models for discrete data.

A sharp inequality for Kendall’s τ and Spearman’s ρ of Extreme-Value Copulas

open access: yesDependence Modeling, 2018
We derive a new (lower) inequality between Kendall’s τ and Spearman’s ρ for two-dimensional Extreme-Value Copulas, show that this inequality is sharp in each point and conclude that the comonotonic and the product copula are the only Extreme-Value ...

Polynomial bivariate copulas of degree five: characterization and some particular inequalities

open access: yesDependence Modeling, 2021
Bivariate polynomial copulas of degree 5 (containing the family of Eyraud-Farlie-Gumbel-Morgenstern copulas) are in a one-to-one correspondence to certain real parameter triplets (a, b, c), i.e., to some set of polynomials in two variables of degree 1: p(

On extended type I generalized logistic distribution

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 57, Page 3069-3074, 2004., 2004
We consider a form of generalized logistic distribution which is called extended type I generalized logistic distribution. Some theorems that relate the distribution to some other statistical distributions are established. A possible application of one of the theorems is included.

A regression characterization of inverse Gaussian distributions and application to EDF goodness‐of‐fit tests

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 9, Page 587-592, 2003., 2003
We give a new characterization of inverse Gaussian distributions using the regression of a suitable statistic based on a given random sample. A corollary of this result is a characterization of inverse Gaussian distribution based on a conditional joint density function of the sample. Application of this corollary as a transformation in the procedure to

Stability of a characterization of normal distributions based on the first two conditional moments

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 10, Page 663-673, 2000., 2000
A characterization of normal distributions of two independent random variables X and Y with a finite E[X2] based on the linearity of E[X | X + Y] and the homoscedasticity of var[X | X + Y] given by Rao (1976) is proved to be stable.

Modelling cascading effects for systemic risk: Properties of the Freund copula

open access: yesDependence Modeling, 2019
We consider a dependent lifetime model for systemic risk, whose basic idea was for the first time presented by Freund. This model allows to model cascading effects of defaults for arbitrarily many economic agents.

Some properties and applications of the stuttering generalized waring distribution

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 12, Issue 3, Page 531-537, 1989., 1989
The Stuttering Generalized Waring Distribution arises in connection with sampling from an urn that contains balls of two colours (black and white) and it can be thought of as an intermingling of generalized Waring streams (Panaretos and Xekalaki [4]). Because of its application potential a study of its properties would be worthwhile.
