Performance of Cross‐Validated Targeted Maximum Likelihood Estimation Background Advanced methods for causal inference, such as targeted maximum likelihood estimation (TMLE), require specific convergence rates and the Donsker class condition for valid statistical esti.....

🚨 New paper in Statistics in Medicine!
We compare TMLE vs CV-TMLE in tricky simulations:
βœ… Misspecification
βœ… Limited overlap
βœ… High dimensions
βœ… Super Learner + cross-validation

Who performs best?
