Qda-class(rrcov)
Qda-class()所属R语言包:rrcov
Class "Qda" - virtual base class for all classic and robust QDA classes
类“QDA”的 - 所有的传统和强大的QDA类的虚基类

描述----------Description----------
The class Qda serves as a base class for deriving all other classes representing the results of classical
类Qda作为一个基类派生其他类的经典
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
center: the group means
center:本组指
cov: the group covariance matrices
cov:该组的协方差矩阵
covinv: the inverse of the group covariance matrices
covinv:本集团的协方差矩阵的逆
covdet: the determinants of the group covariance matrices
covdet:本集团的决定因素,协方差矩阵
method: a character string giving the estimation method used
method:使用一个字符的字符串,给出的估算方法
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。
control: object of class "CovControl" specifying which estimate and with what estimation options to use for the group means and covariances
control:类的对象"CovControl"指定的估计和同组均值和协方差估计可使用
方法----------Methods----------
predict signature(object = "Qda"): 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 scores are 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 = "Qda"):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,则分数。 ,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 = "Qda"): prints the results
显示signature(object = "Qda"):打印结果
summary signature(object = "Qda"): prints summary information
总结signature(object = "Qda"):打印摘要信息
