Beschreibung

"Researchers regularly use administrative micro-data samples to approximate subgroup aggregates from the full population. In this paper, I argue that the most commonly used method to do this is often not optimal. I outline some alternatives and compare their relative performance in selected cases. I also discuss the efect of statistical disclosure control on the aggregated data and how researchers can reduce bias resulting from censoring." (Author's abstract, IAB-Doku, © Springer-Verlag) ((en))
