Plots the Approximate R-Square for the Different Splits
图近似的R平方为不同的分割
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Produces 2 plots. The first plots the r-square (apparent and apparent - from cross-validation) versus the number of splits. The second plots the Relative Error(cross-validation) +/- 1-SE from cross-validation versus the number of splits.
主要生产2图。第一个图的R平方(明显的和明显的 - 从交叉验证)与数分裂。第二图(交叉验证)的相对误差+ / - 1-SE的数量与交叉验证的分裂。
用法----------Usage----------
rsq.rpart(x)
参数----------Arguments----------
参数:x
fitted model object of class rpart. This is assumed to be the result of some function that produces an object with the same named components as that returned by the rpart function. </table>
拟合模型对象的类rpart。这被认为是一些函数,该函数产生的对象具有相同的命名组件rpart函数返回的结果。 </ TABLE>
副作用----------Side Effects----------
Two plots are produced.
两个图。
注意----------Note----------
The labels are only appropriate for the "anova" method.
标签只适用于"anova"方法。
