Diskrete Copula Modelle bilden die Abhängigkeiten zwischen multiplen kategorialen Responses sowie die Einflüsse von Kovariablen auf die jeweiligen Responses ab. In einer Simulationsstudie soll das Verhalten von Schätzern diskreter Copula Modelle bei unterschiedlichen Strukturen der...

There is increasing demand for models of time-varying and non-Gaussian dependencies for mul- tivariate time-series. Available models suffer from the curse of dimensionality or restrictive assumptions on the parameters and the distribution. A promising class of models are the hierarchical...

In this paper, we propose a new approach to estimating sample selection models that combines Generalized Tukey Lambda (GTL) distributions with copulas. The GTL distribution is a versatile univariate distribution that permits a wide range of skewness and thick- or thin-tailed behavior in the data...
