If you have the distance matrix, I think you can input that into nbclust? It may also happen, that there are really now clusters and the increase of the errors sum follows a monotone pattern.

Thing is that it has one mandatory argument <i>data</i> which is used to indicate the dataset. However, in sequence analysis this is the sequences of numbers/symbols rather than the vector(s) of numeric variable values. Even though it is possible to specify the distance matrix, it still requires the actual dataset and in my impression, it is not possible to overcome this. <o:p></o:p></span></div><div class="MsoNormal"><span lang="EN-US" style='color: rgb(31, 73, 125); font-family: "Calibri",sans-serif; font-size: 11pt; mso-fareast-language: EN-US;'>If you have successfully used this package for sequence analysis, could You possibly copy paste the function that You have used for the calculation of the fit indices?<o:p></o:p></span></div><div class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri",sans-serif; font-size: 11pt; mso-fareast-language: EN-US;'>Thank You in advance!<o:p></o:p></span></div><div class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri",sans-serif; font-size: 11pt; mso-fareast-language: EN-US;'>Rimantas<o:p></o:p></span></div><div><div style="border-width: 1pt medium medium; border-style: solid none none; border-color: rgb(225, 225, 225) currentColor currentColor; padding: 3pt 0cm 0cm; border-image: none;"><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><b><span lang="EN-US" style='font-family: "Calibri",sans-serif; font-size: 11pt;'>From:</span></b><span lang="EN-US" style='font-family: "Calibri",sans-serif; font-size: 11pt;'> traminer-users-bounces@lists.r-forge.r-project.org [mailto:traminer-users-bounces@lists.r-forge.r-project.org] <b>On Behalf Of </b>Rimantas Vosylis<br><b>Sent:</b> Wednesday, June 10, 2015 3:36 PM<br><b>To:</b> 'Users questions'<br><b>Subject:</b> Re: [Traminer-users] Antw: selecting the number of clusters<o:p></o:p></span></div></div></div><div class="MsoNormal"><o:p> </o:p></div><div class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri",sans-serif; font-size: 11pt; mso-fareast-language: EN-US;'>Dear Gerhard,<o:p></o:p></span></div><div class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri",sans-serif; font-size: 11pt; mso-fareast-language: EN-US;'>Thank You for this suggestion!<o:p></o:p></span></div><div class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri",sans-serif; font-size: 11pt; mso-fareast-language: EN-US;'>Sincerely<o:p></o:p></span></div><div class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri",sans-serif; font-size: 11pt; mso-fareast-language: EN-US;'>Rimantas<o:p></o:p></span></div><div class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri",sans-serif; font-size: 11pt; mso-fareast-language: EN-US;'><o:p> </o:p></span></div><div><div style="border-width: 1pt medium medium; border-style: solid none none; border-color: rgb(225, 225, 225) currentColor currentColor; padding: 3pt 0cm 0cm; border-image: none;"><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><b><span lang="EN-US" style='font-family: "Calibri",sans-serif; font-size: 11pt;'>From:</span></b><span lang="EN-US" style='font-family: "Calibri",sans-serif; font-size: 11pt;'> <a href="mailto:traminer-users-bounces@lists.r-forge.r-project.org">traminer-users-bounces@lists.r-forge.r-project.org</a> [<a href="mailto:traminer-users-bounces@lists.r-forge.r-project.org">mailto:traminer-users-bounces@lists.r-forge.r-project.org</a>] <b>On Behalf Of </b>Gerhard Wührer<br><b>Sent:</b> Wednesday, June 10, 2015 1:55 PM<br><b>To:</b> <a href="mailto:traminer-users@lists.r-forge.r-project.org">traminer-users@lists.r-forge.r-project.org</a><br><b>Subject:</b> [Traminer-users] Antw: selecting the number of clusters<o:p></o:p></span></div></div></div><div class="MsoNormal"><o:p> </o:p></div><div id="GroupWiseSection_1433933505000_Gerhard.Wuehrer@jku.at_2FDEB7900D0600008FFD18000A004500_"><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>Hello,<o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p> </o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>please try the R - package 'nbclust' do decide how many clusters are feasable.

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.</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'> </span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>Could You perhaps suggest which indexes worked best for You and matched Your expectations / theoretical knowledge and that I could use in my analysis?</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'> </span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>Thank You in advance!!</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'> </span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'> <o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>Sincerely,</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'> </span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>Rimantas Vosylis</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>PhD student, lecturer</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>Insitute of Psychology</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>Faculty of Social Technologies</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>Mykolas Romeris University</span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'> </span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>e-mail: <a href="mailto:rimantasv@mruni.eu">rimantasv@mruni.eu</a></span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'>e-mail2: <u><span style="color: rgb(5, 99, 193);"><a href="mailto:rvosylis@live.com">rvosylis@live.com</a></span></u></span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'> <o:p></o:p></span></div></div><div><div class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span lang="EN-US" style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'> </span><span style='font-family: "Segoe UI",sans-serif; font-size: 10pt;'><o:p></o:p></span></div></div></div></div></div></div></div></div></div></div></body></html>
