Proximities in Columns

If you select the multiple columns model for multiple sources in the Data Format dialog box, then do the following:

1. Select two or more proximities variables. (Each variable is assumed to be a matrix of proximities from a separate source.)
2. Select a rows variable to define the row locations for the proximities in each proximities variable.
3. Select a columns variable to define the column locations for the proximities in each proximities variable. (Cells of the proximity matrix that are not given a row/column designation are treated as missing.)
4. Optionally, select a number of weights variables equal to the number of proximities variables.

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.
