Create Proximities from Data

If you choose to create proximities from the data in the Data Format dialog box, then do the following:

1. If you create distances between variables (see the Create Measure from Data dialog box), select at least three variables. These variables will be used to create the proximity matrix (or matrices, if there are multiple sources). If you create distances between cases, only one variable is needed.
2. If there are multiple sources, select a sources variable.
3. Optionally, choose a measure for creating proximities.

Additionally, you can define a model for the multidimensional scaling, place restrictions on the common space, set convergence criteria, specify the initial configuration to be used, and choose plots and output.
