as.mudfold              Function for calculating MUDFOLD statistics for
                        a given unfolding scale.
coef.mdf                Generic 'coef' method for S3 class '"mdf"'
                        objects.

mudfold                 MUDFOLD: Van Schuur's nonparametric IRT model
                        for dichotomous responses that have been
                        generated by an unfolding process.
mudfold-package         MUDFOLD : A nonparametric unfolding item
                        response theory model for dichotomous
                        preferential-choice data.
mudfoldsim              Function for constructing artificial item
                        response data generated under an unfolding
                        response process. Unfolding processes model the
                        proximity (distance) between person and item
                        parameters.
pick                    Transform items to preference binary data.
plot.mdf                'plot' function for '"mdf"' class objects.
print.mdf               'print' method for '"mdf"' class objects
                        resulted from the 'mudfold' function.
summary.mdf             'summary' method for S3 class '"mdf"' objects.
