Convergence results for patchwork copulas
DOI:10.1016/j.ejor.2015.06.028.png)
Abstract
En 中文
We present a general construction that allows to extend a given subcopula to a copula in such a way that the extension is affine on some specific segments of the copula domain. This construction is hence applied to provide convergence theorems for approximating a copula in strong convergence and in D-1-metric (related to the Markov kernel representation of a copula).
