Abstract:

Copulas have become an important element of best practice for enterprise risk management, displacing in many contexts other more conservative approaches to modelling stochastic dependence. An `ideal' copula should conform to a wide range of problems at hand, being either symmetric or asymmetric, and exhibiting flexible extent of tail dependence. The so-called full-range tail dependence copulas are exactly such a model, and thus they have recently been proved very useful for modeling various dependence patterns in the joint distributional tails.

An inconvenient aspect of the full-range tail dependence copulas is the computational speed, which is acceptable but may not be fast enough for complex applications of modeling high-dimensional dependence structures. In this project, we propose an interpolation approach to overcome the issue. The practical usefulness of our approach will be illustrated with financial data.
