Conditional dependence is expressed as a projection map in the trivariate copula space. The projected copula, its … sample counterpart and the related process are defined. The weak convergence of the projected copula process to a tight … centered Gaussian Process is obtained under weak assumptions on copula derivatives. …

This paper discusses the copula-based approach of a bivariate binary choice model. We derive the marginal effects of …

In this paper, we propose to identify the dependence structure that exists between returns on equity and commodity futures and its development over the past 20years. The key point is that we do not impose any dependence structure, but let the data select it. To do so, we model the dependence...

We find that in general the MALM copula fits our sample data best based on AIC criterion. We find that … the nonexchangeable MALM copula, the asymmetry in the propagation of crisis (bubble) between crude oil and refined product …

in stationary Markov chains using copula functions. We obtain conditions that imply a geometric rate of mixing in models … and tail dependence in the copula function. Rho-mixing, which implies a geometric rate of alpha-mixing, is obtained under … a much weaker condition. We verify one or both of these conditions for a range of parametric copula functions that are …
