I have an issue which I could not solve, although I tried and I got some help on
I am trying to calculate
Mahalanobis distances on a
data.frame, where I have several hundreds of groups and several hundreds of variables.
Whatever I do, I get the
system is computationally singular: reciprocal condition number error.
It is clear that it is singular, but is there any way to get rid of it and run
Mahalanobis? Should I forget solve this using another approach? If yes, then what else to use?
I have uploaded the data file to my FTP: It is a tab delimited txt file with no headers.
I was working with the
StatMatch Mahalanobis (also tried stats
Mahalanobis) function. I have a deadline for this project (not a homework!), and I could always use this function, so I thought I will be able to keep the calculations short, but now I am lost.
