Tips about CART using SPSS Modeler

Hi all,

I am self learning CART with SPSS modeler, for that, I am using some books and replication some examples...

But I have some question about the output of CART analysis. In the output the table of variables was generated a new variable from my target variable ($R-"target_variable"). The values are very similar to original target variable.

So i have some questions about it:

1-I should use this new variable to produce a new model in CART analysis and improve my model?
2- exist some procedure in SPSS modeler to re-analyse this new variable or i have to export as new file?

Any comment i grateful
Thanks in advance.
Regards Rodrigo
