Variable List (CLUSTER command)

The variable list identifies the variables used to compute similarities or distances between cases.

• The variable list is required except when matrix input is used. It must be specified before the optional subcommands.
• If matrix input is used, the variable list can be omitted. The names for the items in the matrix are used to compute similarities or distances.
• You can specify a variable list to override the names for the items in the matrix. This allows you to read in a subset of cases for analysis. Specifying a variable that does not exist in the matrix results in an error.
