Nothing
This package provides different specifications of a Quadrilateral Dissimilarity Model which can be used to fit samedifferent judgments in order to get a predicted matrix that satisfies regular minimality [Colonius & Dzhafarov, 2006, Measurement and representations of sensations, Erlbaum]. From such a matrix, Fechnerian distances can be computed.
