Where does it cut?

Make 0/1 columns diabetic_flag (from diabetic), weekend_flag (from weekend_discharge) and readmit (from readmitted), 1 meaning Yes. The inputs are age, length_of_stay, medications, prior_visits, diabetic_flag and weekend_flag; the answer is readmit.

Train the same depth-1 tree on all rows and store the threshold of its question (input <= threshold), rounded to 1 decimal, in result.
