We present new statistical analyses of data arising from a clinical trial designed to compare
two-stage dynamic treatment regimes (DTRs) for advanced prostate cancer. The trial …

A number of sophisticated estimators of longitudinal effects have been proposed for
estimating the intervention-specific mean outcome. However, there is a relative paucity of …

We study the problem of off-policy evaluation (OPE) in Reinforcement Learning (RL), where
the aim is to estimate the performance of a new policy given historical data that may have …

Multiply robust estimators of the longitudinal g‐formula have recently been proposed to
protect against model misspecification better than the standard augmented inverse …

In previous work, we introduced a framework that combines latent class growth analysis
(LCGA) with marginal structural models (LCGA-MSM). LCGA-MSM first summarizes the …

Targeted maximum likelihood estimation (TMLE) is increasingly used for doubly robust
causal inference, but how missing data should be handled when using TMLE with data …

In conducting studies on an exposure of interest, a systematic roadmap should be applied
for translating causal questions into statistical analyses and interpreting the results. In this …
