Decision tree: Only binary variables (0;1) but splits between 0 and 1

Hey there,

I have a decision-tree with splits between 0 and 1 but my variables only have the characterisitics 0 and 1. 

Bsp: mother-node: variable x --> daughter- node: variable x <=0,5 or > 0,5--> daughter- node: variable x <= 0,25 or > 0,25 usw.

How is that possible and how could I change settings to make the deciontree only split with 0 and 1?

Thanks in advance.

Best

Hi Quinoa (healthy name ;))

this is because the 0,1 are treated as number. You can use the Number to String node before hand on this column, than only the values 0,1 will be considered.
