Class "CovRobust" - virtual base class for robust
“CovRobust类” - 虚基类的鲁棒
译者：生物统计家园网 机器人LoveR
描述----------Description----------
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.
CovRobust是一个虚基类派生的具体类代表不同的多元的位置和分散可靠的估计数。这里是implemeted的可靠的估计数，如show，summary和plot标准的通用方法。
类对象----------Objects from the Class----------
A virtual Class: No objects may be created from it.
可能会从它创建一个虚拟类：没有对象。
插槽----------Slots----------
iter: number of iterations used to compute the estimates
iter：用于计算估计的迭代数
crit: value of the criterion function
crit：价值的标准功能
wt: weights
wt：权重
singularity, X:</dt> from the "Cov" class.
singularity，X：</ dt的>"Cov"类。
扩展----------Extends----------
Class "Cov", directly.
类"Cov"，直接。
方法----------Methods----------
isClassic signature(obj = "CovRobust"): Will return FALSE, since this is a 'Robust' object
isClassic signature(obj = "CovRobust")：将返回FALSE，因为这是一个稳健的对象
getMeth signature(obj = "CovRobust"): Return the name of the particular robust method used (as a character string)
getMethsignature(obj = "CovRobust")：返回的特定使用稳健的方法的名称（作为一个字符串）
show signature(object = "CovRobust"): display the object
显示signature(object = "CovRobust")：显示对象
plot signature(x = "CovRobust"): plot the object
图signature(x = "CovRobust")：绘制对象
getRaw signature(obj = "CovRobust"): Return the object with the reweighted estimates replaced by the raw ones (only relevant for CovMcd, CovMve and CovOgk)
getRawsignature(obj = "CovRobust")：返回对象与重加权的估计所取代，生的（仅相关的CovMcd，CovMve和CovOgk）
