Performs hierarchical clustering of data using specified method and

seraches for optimal cutoff empoying VIF criterion suggested in "Okada Y. et al - Detection of Cluster Boundary in Microarray Data by Reference to MIPS Functional Catalogue Database (2001)".

Namely, it searches cutoff where groups are independent. The techinque uses an econometric approach of verifying that variables in

multiple regression are linearly independent: if all the diagonal
