译者:生物统计家园网 机器人LoveR
描述----------Description----------
The class PcaRobust searves as a base class for deriving all other
类PcaRobust的searves为一个基类导出所有其他
类对象----------Objects from the Class----------
A virtual Class: No objects may be created from it.
可能会从它创建一个虚拟类:没有对象。
插槽----------Slots----------
call: Object of class "language"
call:对象类"language"的
center: Object of class "vector" the center of the data
center:类的对象"vector"的中心的数据
loadings: Object of class "matrix" the matrix
loadings:对象类"matrix"矩阵
eigenvalues: Object of class "vector" the eigenvalues
eigenvalues:对象类"vector"的特征值
scores: Object of class "matrix" the scores - the value of the projected on the space of the principal components data (the centred (and scaled if requested) data multiplied by the loadings matrix) is returned. Hence, cov(scores)
scores:对象的类"matrix"的分数 - 空间的主要组成部分数据(居中(,规模化的要求)的数据乘以loadings矩阵的预计值)被返回。因此,cov(scores)
k: Object of class "numeric" number of (choosen) principal components
k:类"numeric"(选定的)的对象主要组成部分
sd: Object of class "Uvector" Score distances within the robust PCA subspace
sd:对象的类"Uvector"的分数距离内强劲的PCA子空间
od: Object of class "Uvector" Orthogonal distances to the robust PCA subspace
od:对象类"Uvector"正交距离的强劲的PCA子空间
cutoff.sd: Object of class "numeric" Cutoff value for the score distances
cutoff.sd:对象类"numeric"临界值的分数距离
cutoff.od: Object of class "numeric" Cutoff values for the orthogonal distances
cutoff.od:对象的类"numeric"的临界值的垂直距离
flag: Object of class "Uvector" The observations whose score distance is larger than cutoff.sd or whose orthogonal distance is larger than cutoff.od can be considered as outliers and receive a flag equal to zero.
flag:对象类"Uvector"观测,其的得分距离为较大比cutoff.sd或正交距离为大于可以被视为cutoff.od离群值和接收的标志等于零。
n.obs: Object of class "numeric" the number of observations
n.obs:类的对象"numeric"的若干意见
扩展----------Extends----------
Class "Pca", directly.
类"Pca",直接。
方法----------Methods----------
No methods defined with class "PcaRobust" in the signature.
没有定义的方法与类的“PcaRobust”的签名。
