Class "CovNARobust" - virtual base class for robust
“CovNARobust类” - 虚基类的鲁棒
译者:生物统计家园网 机器人LoveR
描述----------Description----------
CovNARobust is a virtual base class used for deriving the concrete classes representing different robust estimates of multivariate location and scatter for incomplete data. Here are implemeted the standard methods common for all robust estimates like show, summary and plot.
CovNARobust是一个虚基类派生的具体类代表不同的多元分布的位置和分散的数据不完整可靠的估计数。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----------
Classes "CovNA" and "CovRobust", directly.
类"CovNA"和"CovRobust",直接。
方法----------Methods----------
plot signature(x = "CovNARobust"): plot the object
图signature(x = "CovNARobust"):绘制对象
summary signature(object = "CovNARobust"): display additional information for the object
总结signature(object = "CovNARobust"):显示附加信息的对象

实例----------Examples----------
data(hbk)
hbk.x <- data.matrix(hbk[, 1:3])
cv <- CovMest(hbk.x) # it is not possible to create an object of[创建一个对象,它是不可能]
# class CovRobust, since it is a VIRTUAL class[类CovRobust,因为它是一个虚拟的类]
cv
summary(cv) # summary method for class CovRobust[汇总类CovRobust方法]
plot(cv) # plot method for class CovRobust[地积类CovRobust方法]
