Hi, I'm using the library cluster to cluster a set of figures (method CLARA). Somebody that it work with clustering would know informs what I make to evaluate the clustering?

Hi, I am not really sure what you want to know. If you simply want to know how to find the resulting clustering, consider help(clara.object). For validation and assessment of the clustering, you might use a silhouette plot, see help(plot.partition), help(partition.object). For more descriptions consider the book of Kaufman and Rousseeuw; some free material is on http://win-www.uia.ac.be/u/statis/index.html (Programs->Clustering) Best, Christian On Thu, 30 Jan 2003, Francisco do Nascimento Junior wrote:> Hi, > I'm using the library cluster to cluster a set of figures (method CLARA). > Somebody that it work with clustering would know informs what I make to > evaluate the clustering? > > Tks VM, > Francisco. > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > Francisco J?nior, > Computer Science - UFPE-Brazil > "One life has more value that the > world whole" > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > http://www.stat.math.ethz.ch/mailman/listinfo/r-help >-- *********************************************************************** Christian Hennig Seminar fuer Statistik, ETH-Zentrum (LEO), CH-8092 Zuerich (currently) and Fachbereich Mathematik-SPST/ZMS, Universitaet Hamburg hennig at stat.math.ethz.ch, http://stat.ethz.ch/~hennig/ hennig at math.uni-hamburg.de, http://www.math.uni-hamburg.de/home/hennig/ ####################################################################### ich empfehle www.boag.de
For Clustering validation it maybe good to refer to "On Clustering Validation Techniques" by Maria Hakidi. It presents a good survey on these kind of techniques. You can even find this an orticles on the subject here http://www.db-net.aueb.gr/mhalk/Publ_maria.htm ______________ Eduardo Miranda Departamento de Inform?tica da FCT/ UNL Quinta da Torre, 2829-516 Caparica, Portugal Tel: +351-21 294 85 36 - Ext. 10731 Fax: +351-21 294 85 41 E-mail: miranda at di.fct.unl.pt http://ctp.di.fct.unl.pt/QUASAR> Date: Fri, 31 Jan 2003 12:34:47 +0100 (CET) > From: Christian Hennig <hennig at stat.math.ethz.ch> > To: Francisco do Nascimento Junior <fnj at cin.ufpe.br> > cc: R-help <R-help at stat.math.ethz.ch> > Subject: Re: [R] Validation of clustering > > Hi, > > I am not really sure what you want to know. > If you simply want to know how to find the resulting clustering, consider > help(clara.object).
