MCD估计的多元分布的位置和分散
译者：生物统计家园网 机器人LoveR
描述----------Description----------
This class, derived from the virtual class "CovRobust" accomodates MCD Estimates of multivariate location and scatter computed by the "Fast MCD" algorithm.
这个类，从虚拟类"CovRobust"衍生容纳MCD估计的多变量的位置和分散计算由“快速MCD算法。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("CovMcd", ...), but the usual way of creating CovMcd objects is a call to the function CovMcd which serves as a constructor.
对象可以通过检测的形式new("CovMcd", ...)创建的，但通常的方式创建“CovMcd对象的功能CovMcd作为构造函数的调用。
