I use several empirical indexes, but they don‘t help me a lot. I use Calinski 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.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Could You perhaps suggest which indexes worked best for You and matched Your expectations / theoretical knowledge and that I could use in my analysis?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Thank You in advance!!<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'>Sincerely,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'>Rimantas Vosylis<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'>PhD student, lecturer<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'>Insitute of Psychology<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'>Faculty of Social Technologies<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'>Mykolas Romeris University<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'>e-mail: <a href="mailto:rimantasv@mruni.eu">rimantasv@mruni.eu</a><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:LT'>e-mail2: <u><span style='color:#0563C1'><a href="mailto:rvosylis@live.com">rvosylis@live.com</a></span></u><o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div></body></html>
