3WaySym-Scal: three-way symbolic multidimensional scaling

Groenen, Patrick; Winsberg, S. - Faculteit der Economische Wetenschappen, Erasmus … - 2006

Multidimensional scaling aims at reconstructing dissimilarities between pairs of objects by distances in a low dimensional space. However, in some cases the dissimilarity itself is not known, but the range, or a histogram of the dissimilarities is given. This type of data fall in the wider class...
