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.
生产2图。 R平方(明显和明显 - 从交叉验证)的第一个图与数量的分裂。第二个图的相对误差(交叉验证)+ / - 1 - SE交叉验证与数分裂。
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>
拟合模型对象类rpart。这被认为是一些功能,产生一个具有相同的命名组件对象rpart函数返回的结果。 </ TABLE>
副作用----------Side Effects----------
Two plots are produced.
两图均产生。
注意----------Note----------
The labels are only appropriate for the "anova" method.
标签只为"anova"适当的方法。
