Package: qdm Version: 0.1-0 Date: 2014-10-16 Title: Fitting a Quadrilateral Dissimilarity Model to Same-Different Judgments Authors@R: c(person("Nora", "Umbach", role = c("aut", "cre"), email = "nora.umbach@web.de"), person("Florian", "Wickelmaier", role = "aut")) Depends: R (>= 3.1.0), stats, graphics Description: 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.
