20.500.12556/RUL-158632 Extending multivariate sub-quasi-copulas In this paper, we introduce patchwork constructions for multivariate quasi-copulas. These results appear to be new since the kind of approach has been limited to either copulas or only bivariate quasi-copulas so far. It seems that the multivariate case is much more involved, since we are able to prove that some of the known methods of bivariate constructions cannot be extended to higher dimensions. Our main result is to present the necessary and sufficient conditions both on the patch and the values of it for the desired multivariate quasi-copula to exist. We also give all possible solutions. mathematics multivariate analysis copulas quasi-copulas multivariate copulas imprecise copulas patchwork matematika multivariatna analiza true false true Angleški jezik Slovenski jezik Članek v reviji 2024-06-18 09:24:43 2024-06-18 09:24:45 2024-07-02 03:35:13 0000-00-00 00:00:00 2024 0 0 14 str. iss. 1, art. 128582 Vol. 540 Dec. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.2 0022-247X 10.1016/j.jmaa.2024.128582 198246659 1-s2.0-S0022247X24005043-main.pdf 1-s2.0-S0022247X24005043-main.pdf 1 AF593403325C9A9BA526BC6CA7AED736 87fd8e398f384536ac55166f768abe229ca80ca280010d5e32313ccd36847719 8f35ad45-2d44-11ef-88cb-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=186323 https://www.sciencedirect.com/science/article/pii/S0022247X24005043 0 4f2beb07-2d44-11ef-88cb-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=186322 Ekonomska fakulteta Fakulteta za matematiko in fiziko 0 0 0
