【目的】研究了具有共同对角面函数的一类多元copula和拟copula的构造。【方法】将已有文献中对角面的概念加以推广,然后定义了一种""运算,基于这种运算建立了构造多元copula和拟copula的方法。【结果】给出了一类具有共同对角面函数的多元copula和拟copula,以及这些copula的性质。【结论】为相关统计建模和金融分析提供了描述某种相依结构的框架。
[Purposes]In this paper,The construction of a class of multivariate copulas and quasi-copulas is investigated with the common diagonal section function.[Methods]The notion of diagonal section on the former literature is generalized,and an operation is put forward which is denoted by "".Then based on this operation,a method of the construction of multivariate copulas and quasi-copulas is studied.[Findings]A class of multivariate copulas and quasi-copulas with the common diagonal section function is given,and its properties is discussed.[Conclusions]These provide some dependence frame for statistical modeling and financial analysis.
