| CovSde-class {rrcov} | R Documentation |
This class, derived from the virtual class "CovRobust"
accomodates Stahel-Donoho estimates of multivariate location and scatter.
Objects can be created by calls of the form new("CovSde", ...),
but the usual way of creating CovSde objects is a call to the function
CovSde which serves as a constructor.
