Causal Effect Estimation with TMLE: Handling Missing Data and Near-Violations of Positivity
Christoph Wiederkehr, Christian Heumann, Michael Schomaker
We evaluate the performance of targeted maximum likelihood estimation (TMLE) for estimating the average treatment effect in missing data scenarios under varying levels of positivit…
Feasible Dose-Response Curves for Continuous Treatments Under Positivity Violations
Han Bao, Michael Schomaker
Positivity violations can complicate estimation and interpretation of causal dose-response curves (CDRCs) for continuous interventions. Weighting-based methods are designed to hand…
A Diagnostic to Find and Help Combat Stochastic Positivity Issues -- with a Focus on Continuous Treatments
Katharina Ring, Michael Schomaker
The positivity assumption is central in the identification of a causal effect, and especially the stochastic variant is an issue many applied researchers face, yet is rarely discus…
Is checking for sequential positivity violations getting you down? Try sPoRT!
Arthur Chatton, Michael Schomaker, Miguel-Angel Luque-Fernandez +2
Background: Sequential positivity is often a necessary assumption for drawing causal inferences, such as through marginal structural modeling. Unfortunately, verification of this a…
