在用随机森林模型randomForest包建立随机森林后建立森林出现了
Call:
randomForest(formula = 替代率 ~ ., data = rw, mtry = 6, ntree = 500, proximity = TRUE)
Type of random forest: classification
Number of trees: 500
No. of variables tried at each split: 6
OOB estimate of error rate: 15.15%
Confusion matrix:
FULL HIGH LOW MID class.error
FULL 2967 22 23 7 0.01722425
HIGH 150 2170 17 269 0.16730622
LOW 37 36 652 178 0.27796235
MID 43 378 76 1133 0.30490798
但是用importance只有MeanDecreaseGini 另一个没有，这个大概是什么情况，谢谢
