Judging a propensity-score specification by balance
The questions ask you to judge a fitted assignment model by the right evidence and to say what it leaves untouched, rather than to restate a definition. The formula returns easily; the habit of reaching for classification accuracy is what needs unlearning.
What this involves
Retrieval after a delay, which is what makes knowledge durable.
Answers here count towards what the system knows about your skills.
What this covers
- Build and judge a propensity-score adjustment
Given an observational study, the learner can say what the propensity score is for, judge a fitted score by balance and overlap rather than by predictive accuracy, and state what it does not repair.
