Confounder selection strategies targeting stable treatment effect estimators

1 code implementation24 Jan 2020 Wen Wei Loh, Stijn Vansteelandt

For these stated reasons, confounder (or covariate) selection is commonly used to determine a subset of the available covariates that is sufficient for confounding adjustment.


Non-linear Mediation Analysis with High-dimensional Mediators whose Causal Structure is Unknown

1 code implementation20 Jan 2020 Wen Wei Loh, Beatrijs Moerkerke, Tom Loeys, Stijn Vansteelandt

With multiple potential mediators on the causal pathway from a treatment to an outcome, we consider the problem of decomposing the effects along multiple possible causal path(s) through each distinct mediator.


Heterogeneous Indirect Effects for Multiple Mediators using Interventional Effect Models

1 code implementation19 Jul 2019 Wen Wei Loh, Beatrijs Moerkerke, Tom Loeys, Stijn Vansteelandt

In this article, we introduce simplified estimation procedures for such heterogeneous interventional indirect effects using interventional effect models.


Randomization inference with general interference and censoring

1 code implementation6 Mar 2018 Wen Wei Loh, Michael G. Hudgens, John D. Clemens, Mohammad Ali, Michael E. Emch

Permitting right censored outcomes is challenging because standard randomization-based tests of the null hypothesis of no treatment effect assume that whether an individual is censored does not depend on treatment.
