Dear Colleagues,
I've been looking for a function that can perform a tree analysis, similar to
CHAID or QUEST.
`ctree' in package `party' implements unbiased recursive partitioning in a
way inspired by CHAID. The methodological details are in
@article{party2006,
key = {566},
author = {Torsten Hothorn and Kurt Hornik and Achim Zeileis},
title = {Unbiased Recursive Partitioning: A Conditional Inference
Framework},
journal = {Journal of Computational and Graphical Statistics},
year = 2006,
note = {in press}
}
A preprint is available from
http://statmath.wu-wien.ac.at/~zeileis/papers/Hothorn+Hornik+Zeileis-2006.pdf
The package vignette explains the operational details.
HTH,
Torsten
The key point is that in this case the variables are not binary but
nominal (10 different values), so "tree" (from the tree package) won't
work. Does anybody know help?
Sincerely,
