Mediation analyses for the effect of antibodies in vaccination

open access: yesJournal of Causal Inference
We review standard mediation assumptions as they apply to identifying antibody effects in a randomized vaccine trial and propose new study designs to allow the identification of an estimand that was previously unidentifiable. For these mediation analyses,

Estimation of time-varying treatment effects using marginal structural models dependent on partial treatment history

open access: yesJournal of Causal Inference
Inverse probability (IP) weighting of marginal structural models (MSMs) can provide consistent estimators of time-varying treatment effects under correct model specifications and identifiability assumptions, even in the presence of time-varying ...

Pointwise adaptive estimation for robust and quantile regression

open access: yes, 2009
A nonparametric procedure for robust regression estimation and for quantile regression is proposed which is completely data-driven and adapts locally to the regularity of the regression function. This is achieved by considering in each point M-estimators
