Re: [R] mahalanobis distance

Thank you for your help... I try other data from my sampling but the determinant is very close to zero. I also tried to generate random numbers using MATLAB and then calculate S=var(x) to no avail. Could you please help me with a pseudo matrix of 4x4 that is gonna work with mahalanobis? Thanks..
