Class "FaCov"
类“FaCov”
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Robust FA based on a robust covariance matrix. Robust FA are obtained by replacing the classical covariance matrix by a robust covariance estimator. This can be one of the available in rrcov estimators, i.e., MCD, OGK, M, S, SDE, or MVE estimator.
强大的FA基于一个强大的协方差矩阵。强大的FA取代经典的协方差矩阵的鲁棒协方差估计。这可以是一个可用的rrcov估计,即,MCD,OGK,M,S,SDE,或MVE估计。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("FaCov", ...). But the usual way of creating FaCov objects is a call to the function FaCov which serves as a constructor.
可以创建对象通过调用的形式new("FaCov", ...)。但通常的方式创建“FaCov对象的功能FaCov作为构造函数的调用。
