Die Humankapitaltheorie sagt voraus, dass mit einem Berufswechsel Hu-mankapitalinvestitionen in berufsspezifische Fähigkeiten erforderlich sind. Insofern sollten sich regionale Unterschiede im Berufsangebot auf das erwartete Einkommen in der Zielregion auswirken. Erfassen bestehende...

The aim of detecting outliers in a multivariate sample can be pursued in different ways. We investigate here the performance of several simultaneous multivariate outlier identification rules based on robust estimators of location and scale. It has been shown that the use of estimators with high...

Graphical modeling as a form of multivariate analysis has turned out to be a capable tool for the detection and modeling of complex dependency structures. Statistical models are related to graphs, in which variables are represented by points and associations between each two of them as lines....

We investigate the combination of the dimension reduction methods SIR (Li, 1991) and DAME (Gather et al., 2001) with fuzzy-clustering to validate a given classification. We consider certain economic variables which are assumed to contain the information relevant to determine the current phase of...

The present method allows to detect outlying observations in data which may be described by a deterministic function plus a stochastic component. This type of functional relationship often occurs in experimental data, in toxicological research, for instance. The Hampel identifier, an outlier...

Methods of dimension reduction are very helpful and almost a necessity if we want to analyze high-dimensional time series since otherwise modelling affords many parameters because of interactions at various time-lags. We use a dynamic version of Sliced Inverse Regression (SIR; Li (1991)), which...

Die vorliegende Arbeit untersucht die Wirkung von Eignungsrückmeldungen nach Potenzialanalysen auf die individuelle Karriereplanung von Mitarbeitern i. S. einer Veränderung der Motivation zur Wahl alternativer Laufbahnen. Die Probanden waren Teilnehmer der Potenzialanalyse „Führung/komplexe...
