Thanks for the fast reply Uwe. My hope in posting this was to find if anyone had already done work (in R) in this direction. So far I wasn't able to find any such relevant code, so I turned to the mailing list.
Regarding new implementations - thanks for offering! - I have already came around one such algorithm - I implemented it, and will probably publish it on my blog <http://www.r-statistics.com/> in the near future. If any one else has any reference to R implementation, it would be most helpful, Tal ----------------Contact Details:------------------------------------------------------- Contact me: tal.gal...@gmail.com | 972-52-7275845 Read me: www.talgalili.com (Hebrew) | www.biostatistics.co.il (Hebrew) | www.r-statistics.com (English) ---------------------------------------------------------------------------------------------- 2010/4/21 Uwe Ligges <lig...@statistik.tu-dortmund.de> > On 21.04.2010 18:15, Tal Galili wrote: > >> Hello all, >> >> I would like to compare the similarity of two cluster solutions using a >> validation criteria (such as Hubert's gamma coefficient, the Dunn index >> the >> corrected rand index and so on) >> >> I see (from here:http://www.statmethods.net/advstats/cluster.html) that >> the function cluster.stats() in the fpc package provides a mechanism >> for comparing 2 cluster solutions - *BUT* - it requires me to give the >> the distance matrix among objects. >> >> *My question *is: What ways can you suggest for comparing two cluster >> solutions, while using the cluster indicators only (i.e: a vector saying >> to >> which cluster each object belongs to), and WITHOUT asking to submit the >> distance matrix between the objects. >> > > Don't know.
