-- After successful execution, this will create a binary representation of the model

-- Step 2 - Score the model- In this step, you will invoke the stored procedure predict_cdr_churn_forst
-- The stored procedure uses the rxPredict function to predict the customers that are likely to churn
-- Results are returned as an output dataset
