“CovClassic类” - 经典估计的多变量
译者:生物统计家园网 机器人LoveR
描述----------Description----------
The class CovClassic represents an estimate of the multivariate location and scatter of a data set. The objects of class CovClassic contain the classical estimates.
类CovClassic多元分布的位置和分散的数据集的估计。对象的类CovClassic包含经典的估计。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("CovClassic", ...), but the usual way of creating CovClassic objects is a call to the function CovClassic which serves as a constructor.
对象可以通过检测的形式new("CovClassic", ...)创建的,但通常的方式创建“CovClassic对象的功能CovClassic作为构造函数的调用。
