WEIGHTS Subcommand (PROXSCAL command)

The WEIGHTS subcommand specifies non-negative weights on the proximities included in the active dataset.

• The number and order of the variables in the variable list is important. The first variable on the WEIGHTS variable list corresponds to the first variable on the PROXSCAL variable list. This is repeated for all variables on the variable lists. Every proximity has its own weight. The number of variables on the WEIGHTS subcommand must therefore be equal to the number of variables on the PROXSCAL variable list.
• Negative weights are not allowed. If specified, a warning will be issued and the procedure will abort.

Example

DATA LIST FILE=’cola.dat’ FREE 
  /object01 TO object14 weight01 TO weight14. 


PROXSCAL object01 TO object14 
  /WEIGHTS=weight01 TO weight14.

• In this example, the VARIABLES subcommand indicates that there are 14 columns per matrix of which the weights can be found in weight01 to weight14.
• weight01 contains the weights for object01, etc.
