people from being individually identified. Microaggregation is a family of methods for statistical disclosure control. The … principle of microaggregation is that confidentiality rules permit the publication of individual records if they are partitioned … (microaggregates), before data publication. This work proposes a column generation algorithm for numerical microaggregation in which …

Microaggregation is one of the most important statistical disclosure control techniques for continuous data. The basic … principle of microaggregation is to group the observations in a data set and to replace them by their corresponding group means …. In this paper, we consider single-axis sorting, a frequently applied microaggregation technique where the formation of …

Microaggregation is a set of procedures that distort empirical data in order to guarantee the factual anonymity of the … scientific research. This paper in- vestigates the effect of microaggregation on the estimation of a linear regression by … induced by various microaggregation techniques. Some microaggrega- tion procedures lead to consistent estimates while others …

The basic principle of microaggregation is to group the observations in a data set and to replace them by their … statistical analyses. The paper deals with the impact of microaggregation on a linear model in continuous variables. We show that …

widely discussed masking procedure is microaggregation, a technique where observations are grouped and replaced with their … corresponding group means. However, while reducing the disclosure risk of data file, microaggregation also affects the results of … statistical analyses. We focus on the effect of microaggregation on a simple linear model, In a previous paper we have shown how …

Micro-aggregation is a frequently used strategy to anonymize data before they are released to the scientific public. A … than one variable can be anonymized by individual micro-aggregation. Data thus distorted may still be used for statistical …
