Like many medical studies, the Berlin Aging Study II (BASE-II) is based on a non-random "convenience sample" of self-recruited participants. To study processes of selectivity in BASE-II, we used an identical questionnaire to compare BASE-II with a large, representative reference study, the...

Empirical analyses of economic inequality, poverty, and mobility in Germany are, to an increas-ing extent, using microdata from the German Federal Statistical Office's contribution to the European Union Statistics on Income and Living Conditions (EU-SILC) as well as data from the German...

Analysen zu Einkommensungleichheit, Armut und Mobilität in Deutschland basieren überwiegend auf den Mikrodaten der amtlichen deutschen Stichprobe der European Union Statistics on Income and Living Conditions (EU-SILC) und des wissenschaftsgetragenen Sozio-oekonomischen Panels (SOEP). Dabei...

The central limit theorem says that, provided an estimator fulfills certain weak conditions, then, for reasonable sample sizes, the sampling distribution of the estimator converges to normality. We propose a procedure to find out what a "reasonably large sample size" is. The procedure is based...

Information on the number of interviewer contacts allows insights into how people's responses to questions on happiness are connected to the difficulty of reaching potential participants. Using the paradata of the German Socio-Economic Panel Study (SOEP), this paper continues such research by...

Based on a representative data set of more than 36 000 original tax report extracts, we develop a microsimulation model that calculates the fiscal impact of changes in the area of tax deductible work-related expenses, in particular expenses for travelling from private home to the place of work,...

Der Beitrag zeigt räumliche Auswertungsmethoden durch die Einbindung von raumrelevanten Indikatoren aus Fernerkundungsdaten in die Daten der Längsschnittstudie Sozio-oekonomisches Panel (SOEP) auf Basis von Geo- Koordinaten. Durch die Verortung von Privathaushalten (ohne Darstellung der...

Using data from the German Socio-Economic Panel, we investigated the role of childbearing history in later life health and mortality, paying particular attention to possible differences by sex and region. Higher parity is associated with better self-rated health in Western German mothers and...

The computation of cross sectional weights in household panels is challenging because household compositions change over time. Sampling probabilities of new household entrants are generally not known and assigning them zero weight is not satisfying. Two common approaches to cross sectional...

Das steigende mittlere Alter bei Geburt wird in der medizinischen Forschung als wichtiger Risikofaktor für die Gesundheit der Neugeborenen erachtet, die über den Indikator Frühgeburt bestimmt werden kann. Die vorliegende Analyse eines Kollektivs von insgesamt 1391 Geburten von Müttern im...
