Hi Thomas, thanks for the comment. I had a similar idea, so got rid of the rounding (these are laboratory measurement based data, thats why I have rounded to only 2 decimal values, but I also tried with 4 and...

Hey Bert, thanks for your fast reply. Yes, based on svd it is singular. The "no way" statement was because of the source of the dataset. I would not expect that. I never used the stats Maha dist calc, but...

Hey David, my answers are delayed here, although I am not using my gmail email address:) Yep thats right, those bands of zeros are one of the most important values to define one group, and have a nice distance from...
