Attributes List Format

When the data table is in the attributes list format, it is converted to a distance matrix and then MDS is applied. The distance matrix is determined by the correlation structure of the data.

JMP generates the distance matrix, or dissimilarity matrix, using the following transformation:

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 that is then used to explore the relationships between crime categories.
