We use the new concept of Levy copula introduced in the literature by Tankov … bivariate variance gamma and bivariate CGMYmodels. To model the dependence structure between underlying assets we use the …

the data using a Generalized Linear model (GLM) incorporating copulas emerge as a more robust technique over traditional … gamma distributions, so as to isolate the level of dependence which is captured in the copula function. The results suggest …

dependence structure among risk factors can be summarised in terms of their cross-moments. This solves the other part of the …

This thesis extends on the use of copulas to simulate the … correlation between obligors. Copulas allow for the creation of one joint distribution using a set of independent distributions …
