Class "Linda" - Robust method for LINear Discriminant Analysis
“琳达” - 强大的线性判别分析方法
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Robust linear discriminant analysis is performed by replacing the classical group means and withing group covariance matrix by robust equivalents based on MCD.
鲁棒线性判别分析进行通过替换的经典组装置和基于MCD强劲当量之内组的协方差矩阵。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("Linda", ...) but the usual way of creating Linda objects is a call to the function Linda which serves as a constructor.
可以通过检测的形式new("Linda", ...)“可是通常的方式创建”Linda对象是Linda作为构造函数的功能调用创建的对象。
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 common covariance matrix
cov:常见的协方差矩阵
ldf: a matrix containing the linear discriminant functions
ldf:矩阵的线性判别函数
ldfconst: a vector containing the constants of each linear discriminant function
ldfconst:一个向量,包含的每个线性判别函数的常数
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。
扩展----------Extends----------
