Assumption-lean inference for generalised linear model parameters

1 code implementation15 Jun 2020 Stijn Vansteelandt, Oliver Dukes

These reduce to standard main effect and effect modification parameters in generalised linear models when these models are correctly specified, but have the advantage that they continue to capture respectively the primary (conditional) association between two variables, or the degree to which two variables interact (in a statistical sense) in their effect on outcome, even when these models are misspecified.

Simulating longitudinal data from marginal structural models using the additive hazard model

1 code implementation10 Feb 2020 Ruth H. Keogh, Shaun R. Seaman, Jon Michael Gran, Stijn Vansteelandt

Simulation studies are a key tool for this, but their use to evaluate causal inference methods has been limited.

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.

Structural Nested Models and G-estimation: The Partially Realized Promise

no code implementations5 Mar 2015 Stijn Vansteelandt, Marshall Joffe

Structural nested models (SNMs) and the associated method of G-estimation were first proposed by James Robins over two decades ago as approaches to modeling and estimating the joint effects of a sequence of treatments or exposures.
