VARIABLES Subcommand (PREFSCAL command)

The variable list identifies the columns in the proximity matrix or matrices that PREFSCAL reads. Each variable identifies one column of the proximity matrix, with each case in the active dataset representing one row.

• Only numeric variables may be specified.
• PREFSCAL reads data row by row, and the columns are represented by the variables on the variable list.

Example

DATA LIST
  /var01 var02.
BEGIN DATA
  1 6
  5 4
  4 2
END DATA.
PREFSCAL var01 TO var02.

• This example specifies an analysis on a 3 × 2 proximity matrix (3 rows and 2 columns).
