Multiply robust estimators in longitudinal studies with missing data under control-based imputation
BIOMETRICS, 80(1).
author keywords: longitudinal clinical trial; longitudinal observational study; semiparametric theory; sensitivity analysis
TL;DR:
A novel estimator inspired by the efficient influence function is obtained, with multiple robustness in the sense that it achieves n1/2-consistency if any pairs of multiple nuisance functions are correctly specified, or if the nuisance functions converge at a rate not slower than n-1/4 when using flexible modeling approaches.

Sensitivity analyses in longitudinal clinical trials via distributional imputation
Liu, S., Yang, S., Zhang, Y., & Liu, G. (2022, November 6). STATISTICAL METHODS IN MEDICAL RESEARCH, Vol. 11.
author keywords: Longitudinal clinical trial; missing data; distributional imputation; multiple imputation; sensitivity analysis
MeSH headings : Models, Statistical; Computer Simulation; Antidepressive Agents / therapeutic use; Monte Carlo Method; Benzenesulfonates
TL;DR:
Distributional imputation is proposed in sensitivity analysis, which imputes each missing value by samples from its target imputation model given the observed data, and is fully efficient with theoretical guarantees.
