Proximities in Columns
If you select the multiple columns model for multiple sources in the Data Format dialog box, then do the following:
- Select two or more proximities variables. (Each variable is assumed to be a matrix of proximities from a separate source.)
- Select a rows variable to define the row locations for the proximities in each proximities variable.
- 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.)
- 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.
