Some New Bivariate Properties and Characterizations Under Archimedean Copula

open access: yesMathematics
This paper considers comparing properties and characterizations of the bivariate functions under Archimedean copula. It is shown that some results of the usual stochastic order for the bivariate functions in the independent case are generalized to the ...

Development and Estimation of Weighted Xgamma Exponential Distribution with Applications to Lifetime Data

open access: yesStatistica
In this article, we introduce a weighted version of the Xgamma exponential distribution, extending its utility in modeling lifetime data. We derive several important distributional properties of the proposed model, including moments, residual life ...

Some Characterizations of Convex Interval Games [PDF]

open access: yes
This paper focuses on two characterizations of convex interval games using the notions of superadditivity and exactness, respectively. We also relate big boss interval games with concave interval games and obtain characterizations of big boss interval ...

Pointvalue characterizations in multi-parameter algebras [PDF]

open access: yes
We extend classical results from the Colombeau algebra, concerning point-value characterizations of generalized functions, to the more general case of multi-parameter (C,E,P)–algebras. Our investigations include considerations about different definitions

Distributional Nikulin-Rao-Robson validity under a novel gamma extension with characterizations and risk assessment [PDF]

open access: yesJournal of Mahani Mathematical Research
In this work, a novel probability distribution is introduced and studied. Some characterizations are presented. Several financial risk indicators, such as the value-at-risk, tail-valueat-risk, tail variance, tail Mean-Variance, and mean excess loss ...

The Lorenz curve in economics and econometrics [PDF]

open access: yes
This paper surveys selected applications of the Lorenz curve and related stochastic orders in economics and econometrics, with a bias towards problems in statistical distribution theory. These include characterizations of income distributions in terms of
