All:
I am trying to implement CHAID decision tree. Can anyone please help me to
know which package can be used for it or lead me to the documentation to
the same.
A CHAID implementation is available on R-Forge at:
https://R-Forge.R-project.org/R/?group_id=343
In recent versions of R you should be able to install the package from
within R via: install.packages("CHAID", repos="http://R-Forge.R-project.org";)
The package contains manual pages.
As an alternative to CHAID you might want to use some more recently
developed statistical algorithms for classification trees, see e.g.,
http://CRAN.R-project.org/view=MachineLearning
In particular, the ctree() function from package "partykit" is based on
similar ideas but is more flexible with respect to the distribution of
dependent and explanatory variables.
I did read a web page says that only the source for the CHAID package is
available. Kindly,advice on the package to be used.
Thanks in advance,
Harmeet
