We compare our empirical findings with a single Gaussian copula, a correlation-weighted average of … Gaussian copulas, the K-copula which directly addresses the nonstationarity of dependencies as a model parameter, and the … skewed Student's t-copula. The K-copula covers the empirical dependence structure on the local scale most adequately, whereas …

This paper extends the analysis of bivariate seemingly unrelated (SUR) Tobit model by modeling its nonlinear dependence structure through copulas. The capability in coupling together the different marginal distributions allows the flexible modeling for the SUR Tobit. The ability in capturing...

Lévy subordinated hierarchical Archimedean copulas (LSHAC) are flexible models in high dimensional modeling. However, there is limited literature discussing their applications, largely due to the challenges in estimating their structures and their parameters. In this paper, we propose a...
