Class "PcaClassic" - Principal Components Analysis
类“PcaClassic” - 主成分分析
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Contains the results of a classical Principal Components Analysis
包含一个经典主成分分析的结果
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("PcaClassic", ...) but the usual way of creating PcaClassic objects is a call to the function PcaClassic which serves as a constructor.
可以通过检测的形式new("PcaClassic", ...)“可是通常的方式创建”PcaClassic对象是PcaClassic作为构造函数的功能调用创建的对象。
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
scale: Object of class "vector" the scaling applied to each variable
scale：类的对象"vector"的缩放适用于每个变量
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----------
getQuan signature(obj = "PcaClassic"): returns the number of
getQuan signature(obj = "PcaClassic")：返回的数量
