Hey guys,
Let say you want to simulate from a multivariate distribution on (\mathbb{R}^d) given by its copula and (d) margins. How would you proceed ? Is there any way to avoid the curse of dimensionality ? The case of most archimedean copulas can be treated using fast multivariate rejection sampling (cf this recent article). How about non-archimedean copulas ?
How fast are the usual methods ? As an example how long would take the computation of a classic basket option price on (d) assets ? Is it a real issue practically ?
Thanks!
