Abstract

This chapter describes microaggregation, a technique for statistical confidentiality that uses aggregation operators. We describe the goals of statistical confidentiality and its application to continuous and categorical data. We show the application of the method to a small publicly available data set. The chapter finishes by reviewing some of the practical problems of the application of microaggregation to statistical disclosure control.
