Hello there,

I am working on an extremely unbalanced two class classification problems. I
wanna use "classwt" with "down sampling" together. By checking the rfNews()
in R, it looks that classwt is not working yet. Then I looked at the
software from Salford. I did not find the down sampling option.  I am
wondering if you have any experience to deal with this problem. Do you know
any method or softwares can handle this problem?

Thank you very much!!

Betty
