WebApr 14, 2024 · IPW can only interpolate. Overlap weights restrict the estimation to the area of overlap, so they do not suffer from this problem. In realistic settings, the true outcome model is likely not linear, so you can't rely on a linear model to get it right. You can use a machine learning method to do g-computation, but then you can't do valid inference.
