Targeted Maximum Likelihood Estimation for Dynamic and Static Longitudinal Marginal Structural Working Models

open access: yesJournal of Causal Inference, 2014
This paper describes a targeted maximum likelihood estimator (TMLE) for the parameters of longitudinal static and dynamic marginal structural models. We consider a longitudinal data structure consisting of baseline covariates, time-dependent intervention

Time-modified Confounding [PDF]

open access: yes, 2009
According to the authors, time-modified confounding occurs when the causal relation between a time-fixed or time-varying confounder and the treatment or outcome changes over time. A key difference between previously described time-varying confounding and

DFW: a novel weighting scheme for covariate balancing and treatment effect estimation

open access: yesFrontiers in Applied Mathematics and Statistics
Estimating causal effects from observational data is challenging due to selection bias, which leads to imbalanced covariate distributions across treatment groups.

Third Variable Effects in Management Studies

open access: yesProblemy Zarządzania, 2016
The article’s aim is to explain the third variable effects in management studies –mediation, suppression, and confounding. Examples of these three types of the third variable effects are based on the European Social Survey (2012) data.

A confounding bridge approach for double negative control inference on causal effects

open access: yesStatistical Theory and Related Fields
Unmeasured confounding is a key challenge for causal inference. In this paper, we establish a framework for unmeasured confounding adjustment with negative control variables.

On the Monotonicity of a Nondifferentially Mismeasured Binary Confounder

open access: yesJournal of Causal Inference, 2020
Suppose that we are interested in the average causal effect of a binary treatment on an outcome when this relationship is confounded by a binary confounder. Suppose that the confounder is unobserved but a nondifferential proxy of it is observed.

Marginal and conditional confounding using logits [PDF]

open access: yes, 2023
This article presents two ways of quantifying confounding using logistic response models for binary outcomes. Drawing on the distinction between marginal and conditional odds ratios in statistics, we define two corresponding measures of confounding ...
