Roche, Jose Manuel (2007). "Methodological proposal for monitoring inequality between social groups: A combined use of Fuzzy Set Theory and Principal Component Analysis" Paper presented at the 4th annual conference of the HDCA, 18-20 September 2007, New York, USA.

This paper proposes a combined use of Fuzzy Set Theory (FST), and Principal Component Analysis (PCA) for the design of a set of indicators for monitoring inequality between social groups. It proposes a methodological solution for the operationalization of the capability approach based on the complementarities of both techniques.
