mahalanodisc | R Documentation |
Vector of Mahalanobis distances or their root. For use in awcoord
only.
mahalanodisc(x2, mg, covg, modus="square")
x2 |
numerical data matrix. |
mg |
mean vector. |
covg |
covariance matrix. |
modus |
"md" (roots of Mahalanobis distances) or "square" (original squared form of 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.
