摘要：
A framework for constructing copulas that can be regarded as a patchwork-like assembly of arbitrary copulas, with nonoverlapping rectangles as patches, is studied in [B. De Baets and H. De Meyer, "Orthogonal grid constructions of copulas," IEEE Trans. Fuzzy Syst., vol. 15, no. 6, pp. 1053-1062, Dec. 2007], where the authors provide sufficient conditions to derive a family of construction methods. Our aim in this paper is to provide a characterization of such constructions.
