Text and/or other creative content from Cluster analysis was copied or moved into Hierarchical clustering with this edit. The former page's history now serves to provide attribution for that content in the latter page, and it must not be deleted as long as the latter page exists.

This is the "main article" for Hierarchical clustering according to the Cluster_analysis page, yet that page actually has more information than this one about Hierarchical clustering algorithms. Surely this should not be. . . Electron100 (talk) 03:05, 21 September 2009 (UTC)[reply]

While I agree that this article is seriously lacking information I believe this page needs to be enhanced rather than merged. Using K-means clustering as an example the cluster analysis page gives an overview, but the main article provides more detailed information. (Humanpowered (talk) 15:30, 23 March 2011 (UTC))[reply]

give example

Dear Sir Please write fluent and understandable about several kind of hierarchical clustering and please give example. — Preceding unsigned comment added by 83.172.123.165 (talk) 19:04, 16 December 2011 (UTC)[reply]

In the section "Metric" am I right that the "i" across which some of the distance metrics are summed is an index of data dimension? i.e. bivariate data will be i = {1, 2}.

If so it might make it clearer to put this definition of i in the text to make it clear to simpletons like me! Also two of the measures (Mahalanobis and cosine) do not sum across i. Does this mean they can only be used for single variate data? If not, is there another formula? — Preceding unsigned comment added by Periololon (talk • contribs) 14:44, 19 March 2012 (UTC)[reply]

V-linkage V-means

I was interested in this technique but I haven't found any reference, searching Google, Google Scholar. We need a source/reference.Moo (talk) 20:25, 11 May 2012 (UTC)[reply]
