The CLUSTER procedure (agglomerative hierarchical techniques) offers different
standardization methods, too (see figure 2-3). Therefore, it is not necessary to use COMPUTE
statements or to run DESC in advance. Unfortunately, QUICK CLUSTER (k-means) does not
provide such possibilities. CLUSTAN and ALMO provide standardization procedures for
agglomerative hierarchical techniques and k-means. CLUSTAN is the most powerful one in
this aspect. However, a syntax language is not integrated in CLUSTAN. Therefore, SPSS and
ALMO are more flexible.
