It is well-known in empirical finance that virtually all asset returns, whether monthly, daily, or intraday, are heavy-tailed and, particularly for stock returns, are mildly but often significantly negatively skewed. However, the tail indices, or maximally existing moments of the returns, can...

MGARCH and standard dynamic copula models are often of little usefulness in such cases. In this paper, we apply a methodology … called the pair-copula decomposition to model the joint conditional distribution of the returns on stocks constituting the …

is the copula philosophy, where the dependency structure is treated entirely separately from marginals. In financial … applications one often needs to work with combinations of marginals of various distributional types, and the copula philosophy is … very attractive as it copes well with heterogeneous marginals. However, with some notable exceptions, the copula approach …

We introduce a general approach to nonlinear quantile regression modelling based on the copula function that defines … the dependence function (or copula). We then deduce the form of the (invariably nonlinear) conditional quantile … relationship implied by the copula. This can be achieved with arbitrary distributions assumed for the marginals. Some properties of …
