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.
