This program reconstructs the positions of stimuli and cases from the preference orders as they are given by the cases. Unfold allows the use of a more-dimensional space. It is especially useful if one wants to find out what are the relevant characteristics that a group of subjects uses to determine their pref­erences among several stimuli.
