Discrete imprecise copulas and alternating sign matrices
Tomaž Košir, Elisa Perrone, Nik Stopar
In this paper, we study discrete quasi-copulas and discrete imprecise copulas of minimal range, which naturally correspond to alternating sign matrices. We show that this family is…
Jordan types for pairs of commuting nilpotent matrices: A survey
Tomaž Košir
The aim of the paper is to survey results on Jordan types for pairs of nilpotent commuting matrices. We also review recent proof of the Box Conjecture on Jordan types that have equ…
Jordan types commuting with a hook partition
Leila Khatami, Tomaž Košir
We give a complete classification of the Jordan types occurring in the nilpotent commutator of a nilpotent matrix whose Jordan type is a hook partition. As a consequence, we also s…
Relation between Blomqvist's beta and other measures of concordance of copulas
Damjana Kokol Bukovšek, Tomaž Košir, Blaž Mojškerc +1
An investigation is presented of how a comprehensive choice of four most important measures of concordance (namely Spearman's rho, Kendall's tau, Spearman's footrule, and Gini's ga…
Reflected maxmin copulas and modelling quadrant subindependence
Tomaž Košir, Matjaž Omladič
Copula models have become popular in different applications, including modeling shocks, in view of their ability to describe better the dependence concepts in stochastic systems. T…
