Hi, I dont know much about CHAID to be honest, but I found a couple of links to introductory material on it: Neural Networks versus CHAID from DM Review White Papers at ZDNet UK and Using CHAID for classification problems

Hey michael, thanks a lot for these links. However I want to know in detail how AID ( automatic interaction detection ) works. I actually know how chaid (chi square automatic interaction detection )works, that is, I know the Chi square part of it. Chi square test is used to find which independent variable is most strongly associated to dependent variable. AID is used for selecting best split with in a selected variable. I want to actually understand the AID part of it in detail. By the way u have made a wonderful discussion board, this will be really helpful for many data miners like me.
