Mahalanobis for AWC
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.
vector of (rooted) Mahalanobis distances.
options(digits=3) x <- cbind(rnorm(50),rnorm(50)) mahalanodisc(x,c(0,0),cov(x)) mahalanodisc(x,c(0,0),matrix(0,ncol=2,nrow=2))
