Simca-class(rrcovHD)
Simca-class()所属R语言包:rrcovHD
Class "Simca" - virtual base class for all classic and robust SIMCA
类“西姆卡” - 的虚基类的所有经典和强大的SIMCA
译者:生物统计家园网 机器人LoveR
描述----------Description----------
The class Simca searves as a base class for deriving all other
类Simca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: the (matched) function call.
call:(匹配)函数调用。
prior: prior probabilities used, default to group proportions
prior:先验概率,默认组的比例
counts: number of observations in each class
counts:在每类若干意见
pcaobj: A list of Pca objects - one for each group
pcaobj:前列腺癌的对象 - 一个为每个组的列表
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
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。
X: the training data set (same as the input parameter x of the constructor function)
X:训练数据集(相同的构造函数的输入参数x)
grp: grouping variable: a factor specifying the class for each observation.
grp:分组变量:指定一个类为每个观测的一个因素。
方法----------Methods----------
predict signature(object = "Simca"): calculates prediction using the results in object. An optional data frame or matrix in which to look for variables with which to predict. If omitted, the training data set is used. If the original fit used a formula or a data frame or a matrix with column names, newdata must contain columns with the same names. Otherwise it must contain the same number of columns,
预测signature(object = "Simca"):计算预测的结果object。一个可选的数据框或矩阵中寻找变量,用以预测。如果省略,则使用训练数据集。 ,如果原始适合用一个公式或数据框或矩阵的列名,newdata必须包含列具有相同的名称。否则,它必须包含相同数量的列,
show signature(object = "Simca"): prints the results
显示signature(object = "Simca"):打印结果
summary signature(object = "Simca"): prints summary information
总结signature(object = "Simca"):打印摘要信息
