20.500.12556/RUL-177622 The exact region determined by Blomqvist’s beta, Spearman’s footrule and Gini’s gamma To quantify the degree of association between random variables, concordance measures are employed. To express such a degree, a single measure might give too much space, so several are used for comparison. In this paper we study the ternary relation between three well-known (weak) concordance measures, namely Blomqvist’s beta, Spearman’s footrule and Gini’s gamma. In other words, given the values of Blomqvist’s beta and Spearman’s footrule, we determine the degree of freedom a copula has at taking the value of Gini’s gamma. We explicitly determine the 3-dimensional region representing the relation. We also provide copulas where bounds of the region are attained. copula dependence concepts supremum and infimum of a set of copulas measures of concordance quasi-copula local bounds concordance measure gini’s gamma Blomqvist’s beta spearman’s footrule kopula koncepti odvisnosti supremum in infimum množice kopul mere skladnosti kvazikopula lokalne meje true false true Angleški jezik Slovenski jezik Članek v reviji 2025-12-30 08:21:48 2025-12-30 08:30:11 2026-01-02 04:04:20 0000-00-00 00:00:00 2026 0 0 13 str. article no. ǂ116861 Vol. 473 Feb. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-06-24 519.2 0377-0427 10.1016/j.cam.2025.116861 240610307 The_exact_region_determined_by_Blomqvist’s_beta,_Spearman’s_footrule_and_Gini’s_gamma.pdf The_exact_region_determined_by_Blomqvist’s_beta,_Spearman’s_footrule_and_Gini’s_gamma.pdf 1 A44D55CFA2169F12CB6BB472C06A06EC de421bb1554846bdf906d44cf98898cdd97a547d52fcbdc10bcad0d1057df731 6431733d-e550-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=224740 https://www.sciencedirect.com/science/article/pii/S0377042725003759?via%3Dihub 0 6f20862e-e550-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=224741 Ekonomska fakulteta 0 0 0
