Variable List Subcommand (PROXSCAL command)

The variable list identifies the columns in the proximity matrix or matrices that PROXSCAL reads. Each variable identifies one column of the proximity matrix, with each case in the active dataset representing one row, unless specified otherwise with the TABLE subcommand. In this case, the variable list identifies whole matrices or sources.

• Only numeric variables can be specified.
• The total number of cases must be divisible by the number of variables. This is not applicable when the TABLE subcommand is used.
• PROXSCAL reads data row by row; the columns are represented by the variables on the variable list. The order of the variables on the list is crucial.

Example

DATA LIST
  /object01 object02 object03 object04. 


BEGIN DATA 
  0 2 6 3
  2 0 5 4
  6 5 0 1
  3 4 1 0
END DATA. 


PROXSCAL VARIABLES=object01 TO object04.

• This example specifies an analysis on a 4×4 proximity matrix.
• The total number of cases must be divisible by 4.
