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...

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...

The selection of copulas is an important aspect of dependence modeling. In many practical applications, only a limited number of copulas is tested, and the modeling applications usually are restricted to the bivariate case. One explanation is the fact that no graphical copula tool exist which...
