Cluster analysis [message #41895]

The cluster analysis in IDL with clust_wts and cluster finds only 8
useful clusters. I can set n_clusters to a greater number, however all
cluster more than 8 useful ones are at locations, that do not contain
any of the samples. Is there any statistical reason that the number of
clusters can never exceed 8?

I have a data set with 24 variables and 7680 samples and would expect
that I can easily find 20 or so different clusters.

Does anybody have better IDL software that does the cluster analysis
properly?

Thank you,
