In chaid analysis, scale independent (predictor) variables are always banded into discrete groups (for example, 0-10, 11-20, 21-30, and so on) prior to analysis you can use the intervals keyword to control the number of discrete intervals for scale predictors.

Classification trees: cart vs chaid when it comes to classification trees, there are three major algorithms used in practice now i get to my point: it appears to me that chaid is most useful for analysis, whereas cart is more suitable for prediction. Chaid's advantages are that its output is highly visual and easy to interpret because it uses multiway splits by default, it needs rather large sample sizes to work effectively, since with small sample sizes the respondent groups can quickly become too small for reliable analysis.
