Statistical Details for Attributes List Format

When the data table is an attributes list, it is converted to a distance matrix and then Multidimensional Scaling is applied. The distance matrix is calculated using Euclidean distance. For each pair of items define the distance between the items by:

Equation shown here

where k is the number of attributes. It is assumed that the measures are on the same scale.

Note: For an advanced example of the MDS platform, see the San Francisco Crime Distances.jmp sample data table and the source script for that table. The script creates the distance matrix using pairwise correlations. The resulting distance matrix is then used to explore the relationships between crime categories.
