Varianzschätzungen für den faktisch anonymisierten Mikrozensus

The scientific use file of the German Microcensus now provides sample information which enables its users to calculate the variance of population estimates. However, not all relevant information on clustering and stratification is at hand. A solution is presented which uses the information of the scientific use file in an efficient way and can be calculated by standard statistical software. Empirical examples are presented, which compare the obtained variance estimates with those presented by the German Statistical Office. We also investigate the behaviour of the linear regression of the design effect which is used as a simple device for variance estimation of the Microcensus.
