Why decision node is not label variable ?

ozgeozyazarozgeozyazar Member Posts: 21 Maven
in Help
I am using decision tree for my classification problem. I decided to use tree to rule to clearly see the results. But realized that decision node is not my target varible. Is it normal or is something wrong ?
(Decision tree with cross validation additionally I decisiden parameters with optimization)
I will be really appreciated if somebody help me on this matter.

Bests,
Özge

    Can you provide XML code (View --> Show Panel --> XML). I tried to replicate using titanic dataset but was able to see my rules with the correct target variable. XML code below.
