Abstract
Public use of microdata files requires preprocessing to protect privacy. Microaggre- gation consists in aggregating data into clusters of size at least k such that the spread between individuals' and centroid cluster values is minimized. This paper proposes an algorithm based on Column Generation to compute lower bounds on the spread.File in questo prodotto:
