inspect the different cluster solutions by content and how meaningful interpretations are. You can also do some kind of x-square test where you align the clusters with variables not used in the cluster analysis. At least you have some kind of face validity.

and harabasz (CH) index, but it has a peak at two cluster solution and the goes down. I also use average shilloute width but it gives me the similar results as CH index. I also run pseudo ANOVA to see which cluster solution explains most variance, but it tells
me the opposite – the more the clusters the higher the pseudo R2 gets. When I look at the various plots (e.g. seqdplot) I see that the most meaningful solutions (I have several types of sequences) lie somewhere between 4-6 clusters.</span><span lang="LT" style="font-size:10.0pt;font-family:"Segoe UI",sans-serif;"></span></p>
