,Nützliches im Umgang mit SPSS,As we saw earlier in the visualizations provided by methods like PCA and SOM, it is often interesting to look for structure, or groupings, in the data. However, these methods do not explicitly define clusters; that is left to the pattern recognition capabilities of the scientist studying the plot.
