 SPSS offers CHAID (Chi-Squared Automatic Interaction Detection) in their Classification Trees module and in the standalone Answer Tree product.

 The CHAID algorithm come from a group of techniques which are often termed "Decision Tree", or "Recursive Partitioning" and you will find other algorithms of this type in the products mentioned ... and in SPSS Clementine.
