system is computationally singular: reciprocal condition number

langvince 
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 after giving it a shot, not a
surprise still singular.
Any idea how to manipulate the data to have it run, or other idea to solve
the problem?

thanks
