Abstract:

Variants of matching and weighting are frequently used to adjust for confounders when estimating average treatment effects in observational studies. In this talk, I'll first briefly review pros and cons of state-of-the-art methods for average treatment effect estimation. I'll then show how some limitations of these methods can be addressed by using numerical optimization tools to directly bound minimax error, and discuss both formal (asymptotic) and empirical advantages of the resulting approach.
