Im Rahmen einer Simulationsstudie werden der Tetrad-Test, das Anpassen eines faktorenanalytischen Messmodels und das Anpassen eines vollständigen Strukturgleichungsmodells verglichen. Es zeigt sich, dass die ersten beiden Verfahren in verschiedenartigen Simulationsszenarien zu ähnlichen...

Purpose One of the currently debated changes in scientific practice is the implementation of data sharing requirements for peer-reviewed publication to increase transparency and intersubjective verifiability of results. However, it seems that data sharing is a not fully adopted behavior among...

We develop an algorithm that incorporates network information into regression settings. It simultaneously estimates the covariate coefficients and the signs of the network connections (i.e. whether the connections are of an activating or of a repressing type). For the coefficient estimation...

The main problem with localized discriminant techniques is the curse of dimensionality, which seems to restrict their use to the case of few variables. This restriction does not hold if localization is combined with a reduction of dimension. In particular it is shown that localization yields...
