Longitudinal Adaptive Experimental Design for Learning Multiple Target Estimands with Semiparametric Efficient Inference

Wenxin Zhang, Mark van der Laan

Adaptive designs are increasingly used in clinical trials and digital experiments to improve estimation efficiency by updating treatment randomization probabilities as data accumulate. While most existing work focuses on settings with a single-stage treatment, adaptive designs fo…

The V-fold jackknife for semiparametric inference: variance estimation, confidence intervals, and simultaneous confidence bands

Yi Li, Ashkan Ertefaie, Mark van der Laan

For decades, the bootstrap has been a default tool for statistical inference because of its broad applicability and minimal analytic requirements. Although its validity is well understood for smooth parametric estimators, its theoretical properties for many modern semiparametric…
