garch-copula

【1】不知道代码对不对？问题不大吧
【2】还有可否教我一下怎么求原始数据的边缘分布，具体代码可以给出吗？采用fitdistrplus包即可
请阅读论文Trivariate analysis of soil ranking-correlated characteristics and its application to probabilistic stability assessments in geotechnical engineering problems http://www.sciencedirect.com/science/article/pii/S003808061300070X 3.6部分的介绍

【3】运行以上代码后，我想取出这两个的copula联合分布，是用mvdc这个函数吗？ mvdc可以构造联合分布函数。including copula name, margins, and paramMargins. http://www.jstatsoft.org/v21/i04/paper
