Gruppenvergleiche bei hypothetischen Konstrukten : die Prüfung der Übereinstimmung von Messmodellen mit der Strukturgleichungsmethodik
Temme, Dirk (contributor); Hildebrandt, Lutz (contributor) - 2008
Comparing groups with respect to hypothetical constructs requires that the measurement models are equal across groups. Otherwise conclusions drawn from the observed indicators regarding differences at the latent level (mean differences, differences in the structural relations) might be severly...

Consumer price adjustment under the microscope : Germany in a period of low inflation
Hoffmann, Johannes (contributor);  … - 2006
We analyse the adjustment of retail and services prices in a period of low inflation, using a set of individual price … data from the German Consumer Price Index which covers the years 1998 to 2003. We strong find evidence of time- and state …-dependent price adjustment. Most importantly, the differences in unconditionalʺ sectoral price flexibility are found to be linked to …

From animal baits to investors' preference : estimating and demixing of the weight function in semiparametric models for biased samples
Ritov, Ya'acov (contributor); Härdle, Wolfgang (contributor) - 2007
We consider two semiparametric models for the weight function in a bias sample model. The object of our interest parametrizes the weight function, and it is either Euclidean or non Euclidean. One of the models discussed in this paper is motivated by the estimation the mixing distribution of...

Estimating probabilities of default with support vector machines
Härdle, Wolfgang (contributor); Moro, Rouslan (contributor) - 2007
This paper proposes a rating methodology that is based on a non-linear classification method, the support vector machine, and a non-parametric technique for mapping rating scores into probabilities of default. We give an introduction to underlying statistical models and represent the results of...

Ein Vergleich des binären Logit-Modells mit künstlichen neuronalen Netzen zur Insolvenzprognose anhand relativer Bilanzkennzahlen
Franken, Ronald (contributor) - 2007
Die Prognose der Insolvenzgefährdung von Unternehmen anhand statistischer Methodik war und ist eine bedeutende Aufgabe empirischer Forschung. Eine Möglichkeit der Beurteilung der finanziellen bzw. wirtschaftlichen Verfassung von Unternehmen stellt die sog. externe Bilanzanalyse anhand...

Kombinierte Liquiditäts- und Solvenzkennzahlen und ein darauf basierendes Insolvenzprognosemodell für deutsche GmbHs
Perederiy, Volodymyr (contributor) - 2007
Eine große Herausforderung der multivariablen Analyse mit bilanziellen Kennzahlen besteht in der Identifikation derjenigen Kennzahlen, die zur besten Modellperformance führen und dabei möglichst leicht interpretierbar und intuitiv bleiben. Die Menge der in Frage kommenden Kennzahlen ist in...

Integrating latent variables in discrete choice models : how higher-order values and attitudes determine consumer choice
Temme, Dirk (contributor); Paulssen, Marcel (contributor);  … - 2007
Integrated choice and latent variable (ICLV) models represent a promising new class of models which merge classic choice models with the structural equation approach (SEM) for latent variables. Despite their conceptual appeal, to date applications of ICLV models in marketing are still rare. The...
