This paper investigates the support set of fitting quasi-nil functions as self-similar fractal sets and provides similar results for both bivariate and multivariate cases.
It is known that for every s is an element of]1, 2[ there is a copula whose support is a self-similar fractal set with Hausdorff -and boxcounting- dimension s. In this paper we provide similar results for (proper) quasi-copulas, in both the bivariate and multivariate cases. (c) 2023 Elsevier B.V. All rights reserved.
