Cov-class(rrcov)
Cov-class()所属R语言包：rrcov
Class "Cov" – a base class for estimates of multivariate
类“COV” - 的多元估计的基类
译者：生物统计家园网 机器人LoveR
描述----------Description----------
The class Cov represents an estimate of the multivariate location and scatter of a data set. The objects of class Cov contain the classical estimates and serve as base for deriving other estimates, i.e. different types of robust estimates.
类Cov多元分布的位置和分散的数据集的估计。类的对象Cov包含了经典的估计和服务为基础派生其他的估计，即不同类型的可靠的估计数。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("Cov", ...), but the usual way of creating Cov objects is a call to the function Cov which serves as a constructor.
对象可以通过检测的形式new("Cov", ...)创建的，但通常的方式创建“Cov对象的功能Cov作为构造函数的调用。

center：位置
n.obs: number of observations used for the computation of the estimates
n.obs：用于计算估计的观测数
mah: mahalanobis distances
mah：马氏距离
det: determinant
det：决定因素
flag: flags (FALSE if suspected an outlier)
flag：标志（FALSE，如果怀疑离群值）
method: a character string describing the method used to
method：字符串描述的方法使用
