CovRobust-class {rrcov} | R Documentation |
CovRobust
is a virtual base class used for deriving the concrete classes
representing different robust estimates of multivariate location and scatter. Here are implemeted the
standard methods common for all robust estimates like show
, summary
and plot
.
The derived classes can override these methods and can define new ones.
A virtual Class: No objects may be created from it.
