Der Aufsatz setzt sich mit dem empirischen Befund auseinander, dass die unterschiedliche Behandlung der kleinen und der großen Gemeinden beim Zensus 2011 zu unterschiedlich hohen Differenzen zwischen Bevölkerungsfortschreibung und Zensus führt. Dabei weisen die großen Gemeinden mit mehr als...

Nonresponse in surveys may result in a distortion of the distribution of interest. In a panel survey the participation behavior in later waves is different from the participation behavior at the start. With register data that cover also the information for non-respondents one can observe a fade...

In self-reported data usually a phenomenon called 'heaping' occurs, i.e. survey participants round the values of their income, weight or height to some degree. Additionally, respondents may be more prone to round off or up due to social desirability. By ignoring the heaping process a severe bias...

The German Microcensus (MC) is a large scale rotating panel survey over three years. The MC is attractive for longitudinal analysis over the entire participation duration because of the mandatory participation and the very high case numbers (about 200 thousand respondents). However, as a...

Aus der statistischen Praxis ist der Computer heute nicht mehr wegzudenken. In der statistischen Lehre dagegen wird der PC häufig noch nicht adäquat genutzt. Dieser Artikel beschreibt Entwicklung, Einsatz und Evaluation eines PC gestützten Lehrkonzepts, das in der statistischen...

The multi-period multinomial Probit model (MMPM) is seen as a flexible tool to explain individual choices among several alternatives over time. There are two versions of this model: a) for each individual the covariates for all alternatives are known and b) for each individual only the...

We propose a new view of initial nonresponse bias in longitudinal surveys. Under certain conditions, an initial bias may "fade-away" over consecutive waves. This effect is discussed in a Markovian framework. A general contraction theorem for time inhomogeneous Markov chains is presented. The...

Modern systems of official statistics require the timely estimation of area-specific densities of sub-populations. Ideally estimates should be based on precise geo-coded information, which is not available due to confidentiality constraints. One approach for ensuring confidentiality is by...
