The theory of conditional copulas provides a means of constructing flexible multivariate density models, allowing for … variables. Further, the use of copulas in constructing these models often allows for the partitioning of the parameter vector …

identify components of mixture copulas. We first consider simulated data samples in which the true dependence structure is … given by a mixture of two parametric copulas: one copula that is presumed to represent the true dependence structure and one … applied to mixtures of copulas with different tail dependence. Several goodness-of-fit tests are shown to hold their nominal …

structure through copulas. The capability in coupling together the different marginal distributions allows the flexible modeling … for the SUR Tobit. The ability in capturing tail dependence is an additionally useful feature of the copulas, especially …

concept of tail copulas as models for different scenarios of joint extreme outcome. For risk management purposes, our findings …
