Hello,
Please cc the list.
Yes, that's what I mean.
Besides, the code as provided doesn't produce an object (search) with a
resid method. Are you sure resid(search) runs without errors?
Hope this helps,
Rui Barradas

Hello Rui,
I use caret and CART
search <- train(Results ~ ., data = training,
method = "rpart",
metric = "MAE",
preProc = c("center", "scale", "zv" ),
getTrainPerf(search)
x=resid(search)
You mean its not the right way for statistical test?

Probably not, R is case sensitive and without loading an external
package that instruction will give an error. Try
wilcox.test(x, y)
with *lower* case *w*.
By the way, why would you test the residuals of regression fits?
It doesn't make sense, especially if the models (algorithms) assume
residuals with mean zero. I suggest you learn more about the techniques
you are using to model your data before trying to test.
Hope this helps,
