Your question is Evaluate Predictive Power of a Model. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You have trained a model and the team wants to know whether it actually predicts the target well, or whether the apparent lift is just noise. The model will be used to rank cases and support decisions, so both discrimination and score quality matter.
How would you evaluate a model's predictive power?
