I think an easy approach in pseudo code (based a bit on python) would be: 1 - Predict a set of known value (X) y_prob = model.predict_proba (X) so you will get the probability per each input in X. 2 - Then for each threshold calculate the output. i.e. If y_prob > threshold = 1 else 0. 3 - Now get the confussion matrix of each vector obtained. how does child poverty affect children
