How to perform cluster analysis in a set:
- With the number of clusters bounded but not specified, e.g. $k\in[3,5]$
- With a bounded abundance of clusters (the number of elements in each of the clusters), e.g. $n_i \geq 4$
FindClusters allows to specify the number of clusters or leave it complitely free. I do not know how to force the number of clusters to belong to the given range.
All the more I do not know how to impose a condition on the minimal abundance of clusters, so that extremely scanty clusters do not arise.
It seams to be a quite reasonable functionality, so maybe I miss something important. I would be grateful for help.
