A Test for Discriminating Between Members of the Odd Weibull-G Family of Distributions. [PDF]
ScientificWorldJournalThe Odd Weibull‐G (OWG) family of distributions has been discussed earlier in the literature. This family of distributions provides a “better fit” in certain practical situations. In a similar fashion, the OWG family of distributions is defined in this article.

New bivariate probability models based on Panjer-type relations
, 2022 Large families of bivariate probability models based on Panjer-type relations are proposed. These relations are generated by differential equations of probability generating functions (p.g.fs), expressed by rational functions that incorporate ...

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

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

On extended type I generalized logistic distribution
International 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.

On a Generalized Raised Cosine Distribution: Some Properties, Characterizations and Applications
Moroccan Journal of Pure and Applied Analysis, 2019 In this paper, we introduced a generalization of the raised cosine distribution. We also provided its several distributional properties and characterizations, including percentiles and some applications.

International 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
International 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.

Maximum asymmetry of copulas revisited
Dependence Modeling, 2018 Motivated by the nice characterization of copulas A for which d∞(A, At) is maximal as established independently by Nelsen [11] and Klement & Mesiar [7], we study maximum asymmetry with respect to the conditioning-based metric D1 going back to Trutschnig [
