RT info:eu-repo/semantics/article T1 A family of distances for preference–approvals A1 Albano, Alessandro A1 García Lapresta, José Luis A1 Plaia, Antonella A1 Sciandra, Mariangela K1 Preferencia–aprobaciones K1 Preference–approvals AB A preference–approval on a set of alternatives consists of a weak order on that set and, additionally, a cut-off line that separates acceptable and unacceptable alternatives. In this paper, we propose a new method for defining the distance between preference–approvals taking into account jointly the disagreements in preferences and approvals for each pair of alternatives. The proposed distance is compared to the existing distance functions to deal with clustering problems. Specifically, we prove that our metric improves the estimated clusters in terms of both stability and accuracy.
