Subject: rpart with only two small groups
Hello R-User!
I try to do the following:
New<-iris[c(1:7,90:97),1:5]
New.rpart<-rpart(Species~., data=New, method="class")
New.rpart
n= 15
node), split, n, loss, yval, (yprob)
* denotes terminal node
1) root 15 7 versicolor (0.4666667 0.5333333) *
Does it mean it is not possible to find a variable that splits my groups or
are my groups just to small?
Is there a way to find out the variable that splits my groups best?
Thanks in advance for help.
