Vector of Mahalanobis distances or their root. For use in awcoord only.
mahalanodisc(x2, mg, covg, modus="square")numerical data matrix.
mean vector.
covariance matrix.
"md" (roots of Mahalanobis distances) or "square" (original squared form of Mahalanobis distances).
vector of (rooted) Mahalanobis distances.
The covariance matrix
is inverted by use of
solvecov, which can be expected to give
reasonable results for singular within-class covariance matrices.
