CovMest-class {rrcov} | R Documentation |
This class, derived from the virtual class "CovRobust" accomodates constrained M-Estimates of multivariate location and scatter based on the translated biweight function (‘t-biweight’) using a High breakdown point initial estimate (Minimum Covariance Determinant - ‘Fast MCD’)
Objects can be created by calls of the form new("CovMest", ...)
,
but the usual way of creating CovMest
objects is a call to the function
CovMest
which serves as a constructor.
