WebIn this package several bivariate copula families are included for bivariate and multivariate analysis using vine copulas. It provides functionality of elliptical (Gaussian and Student-t) as well as Archimedean (Clayton, Gumbel, Frank, Joe, BB1, BB6, BB7 and BB8) copulas to cover a large range of dependence patterns. WebCopula函数的概念由Sklar于1959年提出,它是将各单变量边缘分布与联合分布连接起来的函数,使得边缘分布和联合分布函数的选择更加灵活[5].Copula函数被广泛应用于许多领域的相关关系建模中[6-7],但当维数增加时,copula的参数估计变得困难,因此 Joe[8],Bedford[9],Aas[10]等提出并发展了vine copula.Vine ...
