In financial and actuarial sciences, knowledge about the dependence structure is of a great importance. Unfortunately this kind of information is often scarce. Many research has already been done in this field e.g. through the theory of comonotonicity. It turned out that a comonotonic dependence...

We introduce and discuss the test space problem as a part of the whole copula fitting process. In particular, we explain how an efficient copula test space can be constructed by taking into account information about the existing dependence. Although our model is developed in a bivariate...

We introduce and discuss a new parametric copula builder which is named the “? construction method”. The methodology is explained and illustrated using 3 types of ? functions. It shows that the ? method has strong visual advantages for recognizing key dependence characteristics and importing...
