Hi, there:
I am looking for a regression modeling (like regression trees) approach for
a large-scale industry dataset. Any suggestion on a package from R or from
other sources which has a decent accuracy and scalability? Any
recommendation from experience is highly appreciated.
Thanks,
Weiwei

Please advise me how to use 'R' to model this data set (Actually, i
