Prediction decimal(Real) data by using decision tree and other algorithms

mohammadrashki

I Want to predict about 100 real data by rapidminer with new method like Decision trees, Random Forest and ...
But many of method have error that data must be binominal or other , and dont predict real data. 
Please Help me and say Steps for Prediction for it by dicision trees and random forest 
I have begin Rapidminer newly.

@mohammadrashki ,
you need to set the measure to "least squares" in order to allow RF and Decision Trees to predict numerical values.

Best,
