Fitting a Quadrilateral Dissimilarity Model to Same-Different Judgments.

http://cran.r-project.org/web/packages/qdm

This package provides different specifications of a Quadrilateral Dissimilarity Model which can be used to fit same-different 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.
