Proximity matrices are frequently asymmetric and analyzed by using the additive decomposition into symmetric and skew-symmetric components. A strategy for a preliminary graphical description and clustering of the two components based on some recent methods is presented. An empirical application allows to emphasize the advantages and the effectiveness of the proposal.

Abstract
Proximity matrices are frequently asymmetric and analyzed by using the additive decomposition into symmetric and skew-symmetric components. A strategy for a preliminary graphical description and clustering of the two components based on some recent methods is presented. An empirical application allows to emphasize the advantages and the effectiveness of the proposal.File allegati a questo prodotto
