您好。我有两种思路,
第一种是换个包,参考https://stackoverflow.com/questi ... ula-trivariate-in-r的回答,There are many other vine copula packages, but not sure if they will be good for your question, for example, vinereg (for fitting regression D-vine copula), vinecopulib (similar to the VineCopula but take into account the marginals).
第二种是积分。密度函数一般而言性质都比较好,考虑到您的遇到的是高维问题,我的建议是sparse gird(或者您搜 smolyak construction),尽管我只用matlab写过。
