用R做CART one tree regression, 10 fold cross validation的结果包括xerror和
xstd. 用xpred.rpart 输出cross validation的具体数值,然后用以下公式计算xerror
,得到的结果和R直接输出的不一样。是我公式用错了吗?正确的公式是什么呢?xstd
又是怎么算的,网上都找不到。多谢!

我查了一下文件 /var/dt/Xerrors,发现这个:
XIO: fatal IO error 131 (Connection reset by peer) on X server "test-pc:13.
0"
after 4041 requests (4026 known processed) with 0 events remaining.
