Abstract: Abstract A special case of SSA where we have as data only proximities between two sets but not within these sets is investigated formally and as a psychological model. The approach is known as unfolding. The two sets are usually individuals and choice objects, which are represented together as points in a multidimensional space. This psychologically interesting model is subject to many potential degeneracies.
