Hi Everyone,
I'm working on building some classification trees, and up to this point
I've been using rpart. However, I recently discovered the tree package,
and found that it had some useful functions (in particular deviance(),
which I would really like to use for my project). I can't seem to find
an equivalent function for rpart. I've considered using tree() in place
of rpart(), but I read an old post on this list that recommended using
rpart() as tree() was built for bug-checking in S. So, to summarize:
Is there a way to compute deviance for an rpart object?
If not, would it be a bad idea to use tree() in place of rpart()? My
rpart models are currently quite large and take ~ 15 minutes to run...
Thanks everyone!
