CovNASest-class: S Estimates of Multivariate Location and Scatter for...

In rrcovNA: Scalable Robust Estimators with High Breakdown Point for Incomplete Data

S Estimates of Multivariate Location and Scatter for incomplete data

Description

This class, derived from the virtual class "CovRobust" accomodates S Estimates of multivariate location and scatter computed by the ‘Fast S’ or ‘SURREAL’ algorithm.

Objects from the Class

Objects can be created by calls of the form new("CovSest", ...), but the usual way of creating CovSest objects is a call to the function CovSest which serves as a constructor.

Slots

iter, crit, wt:

from the "CovRobust" class.

call, cov, center, n.obs, mah, method, singularity, X:

from the "Cov" class.

Extends

Class "CovRobust", directly. Class "Cov", by class "CovRobust".

Methods

No methods defined with class "CovSest" in the signature.
