Die Studie untersucht Determinanten der Studiendauer und der Endnote von Kölner Studierenden im wirtschaftswissenschaftlichen Grundstudium auf Grund einer Auswertung der Prüfungsdaten. Die Ergebnisse führen zu Empfehlungen für den individuellen Aufbau des Studiums und die Konzeption...

Diese Studie untersucht Determinanten der Studiendauer und der Endnote von Kölner Studierenden im wirtschaftswissenschaftlichen Hauptstudium auf Grund einer Auswertung der Prüfungsdaten. Sie setzt eine entsprechende Studie über das Grundstudium (Mosler und Savine, 2004) fort. Die Ergebnisse...

Nonlinear autoregressive Markov regime-switching models are intuitive and frequently proposed time series approaches for the modelling of electricity spot prices. In this paper such models are compared to an ordinary linear autoregressive model with regard to their forecast performance. The...

Compared with the broad supply of literature measuring socioeconomic gradients in the distribution of health, only little is know about the life course perspective regarding income related inequalities. This article combines the reowned concentration index approach with semiparametric estimation...

Trimmed regions are a powerful tool of multivariate data analysis. They describe a probability distribution in Euclidean d-space regarding location, dispersion, and shape, and they order multivariate data with respect to their centrality. Dyckerhoff and Mosler (201x) have introduced the class of...

The Gini index and the Gini mean difference of a univariate distribution are extended to measure the disparity of a general d-variate distribution. We propose and investigate two approaches, one based on the distance of the distribution from itself, the other on the volume of a convex set in (d...
