PcaCov-class(rrcov)
PcaCov-class()所属R语言包:rrcov
Class "PcaCov" - Robust PCA based on a robust covariance matrix
类“PcaCov” - 强大的基于鲁棒协方差矩阵的PCA
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Robust PCA are obtained by replacing the classical covariance matrix by a robust covariance estimator. This can be one of the available in rrcov estimators, i.e. MCD, OGK, M, S or Stahel-Donoho estimator.
鲁棒PCA取代经典的协方差矩阵的鲁棒协方差估计。这可以是一个可用的rrcov估计量,即MCD,OGK,M,S或Stahel Donoho提出估计。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("PcaCov", ...) but the usual way of creating PcaCov objects is a call to the function PcaCov which serves as a constructor.
可以通过检测的形式new("PcaCov", ...)“可是通常的方式创建”PcaCov对象是PcaCov作为构造函数的功能调用创建的对象。
插槽----------Slots----------
quan: Object of class "numeric"
quan:对象类"numeric"的
from the "Pca" class.
从"Pca"类。
扩展----------Extends----------
Class "PcaRobust", directly. Class "Pca", by class "PcaRobust", distance 2.
类"PcaRobust",直接。类"Pca",类的“PcaRobust”,距离2。
方法----------Methods----------
getQuan signature(obj = "PcaCov"): ...
getQuan signature(obj = "PcaCov")...
