MVE多元分布的位置和分散的估计
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 MVE Estimates of multivariate location and scatter computed by the "Fast MVE" algorithm.
这个类,从虚拟类"CovRobust"衍生容纳多元分布的位置和分散计算由“快MVE”算法的的MVE估计的。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("CovMve", ...), but the usual way of creating CovMve objects is a call to the function CovMve which serves as a constructor.
对象可以通过检测的形式new("CovMve", ...)创建的,但通常的方式创建“CovMve对象的功能CovMve作为构造函数的调用。
