FaRobust-class {robustfa}

Class "FaRobust"

Description

Class "FaRobust" is a virtual base class for all robust FA classes. Currently the only available robust FA class is "FaCov". The class "FaRobust" serves as a base class for deriving all other classes representing the results of the robust Factor Analysis methods.

Objects from the Class

A virtual Class: No objects may be created from it.
