Hello.

I know that there exist a function called mclust that works with S-PLUS for Model-based Cluster Analysis according to an article by Fraley and Raftery from 1998. Sense I´m no expert when it comes to clustering, it´s hard for me to be more specific. But in the article model-based cluster analysis is described as "In model-based cluster analysis data are represented by a mixture model in which each component corresponds to a different cluster. Models with varying geomteric properties are obtained through Gaussian compnents with different parameterixations and cross-cluster constraints..." I hope this gives you a clue to what I`m after. I appreciate all the help and suggestions I can get.

Best Regards

Can you be a little more specific please, Lina?
Clustering can have about three different meanings in a statistical context, and that's just off the top of my head, that are quite different.
