Variable List (QUICK CLUSTER command)
The variable list identifies the clustering variables.
- The variable list is required and must be the first specification on QUICK CLUSTER.
- You can use keyword ALL to refer to all user-defined variables in the active dataset.
- QUICK CLUSTER uses squared Euclidean distances, which equally weight all clustering variables. If the variables are measured in units that are not comparable, the procedure will give more weight to variables with large variances. Therefore, you should standardize variables measured on different scales using procedure DESCRIPTIVES before performing QUICK CLUSTER.
