Freedom in constructing quasi-copulas vs. copulasOmladič, Matjaž (Avtor) Stopar, Nik (Avtor) copulasquasi-copulasshuffles of minpatchlatticesThe main goal of this paper is to study the extent of freedom one has in constructing quasi-copulas vs. copulas. Specifically, it exhibits three construction methods for quasi-copulas based on recent developments: a representation of multivariate quasi-copulas by means of infima and suprema of copulas, an extension of a classical result on shuffles of min to the setting of quasi-copulas, and a construction method for quasi-copulas obeying a given signed mass pattern on a patch.20252025-04-11 13:18:18Članek v reviji168411UDK: 519.2ISSN pri članku: 0165-0114DOI: 10.1016/j.fss.2025.109399COBISS_ID: 231931139sl
