Outstanding, I'll have to check these out.  I'm not as concerned about the
free part, but it never hurts.  

I appreciate the help, many thanks.

Cheers,

Kirk

Nothing found in stata, ... but if the issue is getting hold of a free 
application to do this you have the choice of:
- the R program, package 'tree'
- programme SIPINA (limited version) available from 
http://eric.univ-lyon2.fr/~ricco/sipina.html
- There are a few programmes on the net that run the C4.5 algorithm.

All of these have a fairly steep learning curve.  Many on the list 
would advise against using such data-driven approaches.

Does anyone happen to know how to do AID/CHAID/XAID analyses or anything
similar in Stata 8.0?  So far, the only thing I can find is that SPSS 
has
this type of analysis, but that's of little use to me.....
