A simple non-parametric goodness-of-fit test for elliptical copulas

open access: yesDependence Modeling, 2017
In this paper, we propose a simple non-parametric goodness-of-fit test for elliptical copulas of any dimension. It is based on the equality of Kendall’s tau and Blomqvist’s beta for all bivariate margins.

Strictly Archimedean copulas with complete association for multivariate dependence based on the Clayton family

open access: yesDependence Modeling, 2018
The family of Clayton copulas is one of the most widely used Archimedean copulas for dependency measurement. A major drawback of this copula is that when it accounts for negative dependence, the copula is nonstrict and its support is dependent on the ...

Cerebrospinal Fluid Tau, p-Tau 181 and Amyloid-beta(38/40/42) in Frontotemporal Dementias and Primary Progressive Aphasias [PDF]

open access: yes, 2010
Background/Aims: We determined cerebrospinal fluid (CSF) concentrations of amyloid-beta(A beta)(1-38), A beta(1-40), A beta(1-42), total tau and phospho-tau (p-tau) in order to study their differential expression in frontotemporal dementia (FTD, n = 25 ...

On Concordance Measures for Discrete Data and Dependence Properties of Poisson Model

open access: yesJournal of Probability and Statistics, 2009
We study Kendall's tau and Spearman's rho concordance measures for discrete variables. We mainly provide their best bounds using positive dependence properties. These bounds are difficult to write down explicitly in general.

Unveiling the Interplanetary Solar Radio Bursts of the 2024 Mother’s Day Solar Storm

open access: yesThe Astrophysical Journal Letters
We report on a comprehensive study of interplanetary type III radio bursts linked to X-class solar flares from NOAA active region 13664, which instigated the intense 2024 Mother’s Day solar storm, marked by a geomagnetic storm of −412 nT, the strongest ...

Kendall’s tau for elliptical distributions. In

open access: yes, 2003
. By using well known properties of elliptical distributions we show that the relation between Kendall’s tau and the linear correlation coefficient for bivariate normal distributions holds more generally (subject to only slight modifications) for the ...
