Hi Zindi,
If the data is based on real occurrences, how is it possible that we can know if a policy that hasn't even started has lapsed. There's data for May (because there is a one month grace period), July and August in the test set. How is this being checked against prediction since the policy hasn't even taken effect?
How do you know there is a grace period?
