Description Objects from the Class Slots Extends Methods Author(s) References See Also Examples

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.
