本文基于测度迁移理论,引入了具有给定多元边际的多元分布的向量Copula,并建立了Sklar定理的向量版本。后者为使用向量Copula来刻画有限个随机向量之间的非线性或秩相关(对向量内相关具有鲁棒性),以及构造具有任意给定非重叠多元边际的多元分布提供了理论依据。我们构造了向量Copula的椭圆族和Kendall族,导出了它们的密度,并给出了由它们生成数据的算法。通过对国际金融传染的程式化分析,说明了向量Copula的使用。

英文摘要:
This paper introduces vector copulas associated with multivariate distributions with given multivariate marginals, based on the theory of measure transportation, and establishes a vector version of Sklar's theorem. The latter provides a theoretical justification for the use of vector copulas to characterize nonlinear or rank dependence between a finite number of random vectors (robust to within vector dependence), and to construct multivariate distributions with any given non overlapping multivariate marginals. We construct Elliptical and Kendall families of vector copulas, derive their densities, and present algorithms to generate data from them. The use of vector copulas is illustrated with a stylized analysis of international financial contagion.
