WebOct 2, 2024 · All we’re doing for IPW is using logistic regression to create propensity scores, and the code below shows how to do that. Behind the scenes you’re moving from log odds (they’re linear!) to odds (they’re interpretable-ish) to probabilities (they’re super interpretable!), but you don’t need to worry about that. WebThe Inverse Probability Weighted Estimator (IPWE) can be unstable if estimated propensities are small. If the probability of either treatment assignment is small, then the …
