ALSCAL performs metric or nonmetric Multidimensional Scaling and Unfolding with individual differences options. It can analyze one or more matrices of dissimilarity or similarity data.

The analysis represents the rows and columns of the data matrix as points in a Euclidean space.

If a row and column are similar, then their points are close together, while if the row and column are dissimilar, they are far apart.
