Like other data quality dimensions, the concept of accuracy is often adopted to characterise a particular data set. However, its common specification basically refers to statistical properties of estimators, which can hardly be proved by means of a single survey at hand. This ambiguity can be...

In this paper R2-type measures of the explanatory power of multivariate linear and categorical probit models proposed in the literature are reviewed and their deficiencies are discussed. It is argued that a measure of the explanatory power should take into account the components which are...

Soziale Erwünschtheit kann als Tendenz verstanden werden, scheinbar gesellschaftlich akzeptierte Antworten bei einer Befragung zu geben. Basierend auf den Analysen von Paulhus (1984) wird zwischen zwei Dimensionen unterschieden, der Selbst- und Fremdtäuschung. In Deutschland gibt es in der...

Im Januar des Jahres 2008 begann die Feldarbeit der 25. Welle des SOEP. Im Jahr 2009 werden damit etwa 2 500 anonymisierte Datensätze von Personen zur Auswertung zur Verfügung stehen, die seit 1984 ununterbrochen an 25 Befragungen in den westdeutschen SOEP-Teilstichproben A und B teilgenommen...

Die Daten des Sozio-oekeonomischen Panels (SOEP) werden seit 1984 auf Grundlage eines mit dem Befragungsinstitut Infratest abgestimmten Erhebungskonzepts jährlich erhoben. Erfasst werden die Daten zentral in München bei TNS Infratest, aufbereitet in München und beim DIW Berlin, um dann...

We propose a generalized estimating equations approach to the analysis of the mean and the covariance structure of a bivariate time series process of panel data with mixed continuous and discrete dependent variables. The approach is used to jointly analyze wage dynamics and the incidence of...

This article proposes an estimation approach for panel models with mixed continuous and ordered categorical outcomes based on generalized estimating equations for the mean and pseudo-score equations for the covariance parameters. A numerical study suggests that efficiency can be gained as...

Design-based estimators of totals, means or proportions in finite populations generally are functions of weighted sums. If each element selected into the sample is also observed, then for the calculation of the pi-estimator these weights are just the inverse inclusion probabilities of the...
