Example (CLUSTER command)

CLUSTER V1 TO V4
  /PLOT=DENDROGRAM
  /PRINT=CLUSTER (2 4).

• This example clusters cases based on their values for all variables between and including V1 and V4 in the active dataset.
• The analysis uses the default measure of distance (squared Euclidean) and the default clustering method (average linkage between groups).
• PLOT requests a dendrogram.
• PRINT displays a table of the cluster membership of each case for the two-, three-, and four-cluster solutions.

Used with the PROXIMITIES command to create distances
