When Prediction Error Is Not Enough: Evaluating Nuisance-Function Prediction for Causal Estimation
A new arXiv preprint (arXiv:2609.00071v1) reports that prediction error is not a reliable proxy for causal estimator quality, based on Monte Carlo simulations comparing OLS, GAMs, XGBoost, and Double …
