How far are -dimensional copulas with uniform -marginals from (total) independence?
Damjana Kokol Bukovšek, Nik Stopar, Wolfgang Trutschnig
We consider the family of all -dimensional copulas whose -dimensional marginals are all equal to the -dimensional product copula $Π_{d-…
Dense alternating sign matrices and imprecise copulas
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 identify dense alternati…
Unital compressed commuting graph of matrices over a finite prime field
Ivan-Vanja Boroja, Damjana Kokol Bukovšek, Nik Stopar
In this paper we completely describe the unital compressed commuting graph of the ring of matrices over the finite prime field $\mathrm…
The exact region determined by Spearman's footrule, Gini's gamma and Kendall's tau
Damjana Kokol Bukovšek, Petra Lazić, Blaž Mojškerc +1
Concordance measures are used to express the degree of association between random variables. Practitioners may use several distinct concordance measures to narrow the space of poss…
