TheOrdinals: Aggregation and Consensus Methods for Preference-Approvals

Tools for aggregating ordinal preference data into a group consensus. The package implements DIVA (Divide and Conquer for Preference-Approvals), a distance-based aggregation method for preference-approvals, that is, preference data in which voters express both a (weak) ranking and an approval of the alternatives. The consensus is the preference-approval minimising the average distance to the set of voters, measured through the family of distances of Erdamar, Garcia-Lapresta, Perez-Roman and Sanver (2014) <doi:10.1016/j.mathsocsci.2013.10.005>. Methods and applications are described in Albano and Romano (2026) <doi:10.1007/s11634-025-00663-4>. The package is designed to be extended with further methods for ordinal preference data.
