This paper presents Granger mediation analysis, a new framework for causal mediation analysis of multiple time series. This framework is motivated by a functional magnetic resonance imaging (fMRI) experiment where we are interested in estimating the mediation effects between a randomized stimulus time series and brain activity time series from two brain regions. The independent observation assumption is thus unrealistic for this type of time‐series data. To address this challenge, our framework… 

Bayesian network mediation analysis with application to the brain functional connectome

An integrative mediation analysis under a Bayesian paradigm with networks entailing the mediation effect is proposed and the superiority of this model in estimating different effect components and selecting active mediating network structures is shown.

Mediation Analysis with Multiple Exposures and Multiple Mediators

A mediation analysis approach is proposed for multiple exposures, multiple mediators, and a continuous scalar outcome under the linear structural equation modeling framework. It assumes that there

Functional Data Analysis with Causation in Observational Studies: Covariate Balancing Functional Propensity Score for Functional Treatments

Functional data analysis, which handles data arising from curves, surfaces, volumes, manifolds and beyond in a variety of scientific fields, is a rapidly developing area in modern statistics and data

Understanding Between-Person Interventions With Time-Intensive Longitudinal Outcome Data: Longitudinal Mediation Analyses

The importance of considering the timing of the causal effects of a between-person intervention X, on M and Y, resulting in a deeper understanding of mediation is highlighted, to pay more attention to temporal dynamics in the causal analysis of interventions.

Average Treatment Effect Estimation in Observational Studies with Functional Covariates

Various state-of-art propensity score estimation methods for multivariate data to functional data are generalized and applied to a real-world dataset to study the causal effect of duloxitine on the pain relief of chronic knee osteoarthritis patients.



Estimating Mediation Effects under Correlated Errors with an Application to fMRI

This paper proposes a two-layer SEM framework for mediation analysis that provides valid inference even if correlated additive errors are present, and introduces a linear mixed effects SEM with an innovation to estimate the unknown correlation parameter in the first layer, instead of sensitivity analysis.

This work provides the first application of causal inference to the FDA framework and is applied to data from a functional magnetic resonance imaging study of thermal pain that sought to determine whether activation in certain brain regions mediated the effect of applied temperature on self-reported pain.

High-dimensional multivariate mediation with application to neuroimaging data.

A novel method for identifying potential mediators in this setting called the directions of mediation (DMs) is introduced, which linearly combine potential mediator components into a smaller number of orthogonal components, with components ranked based on the proportion of the LSEM likelihood each accounts for.

Causal Inference for fMRI Time Series Data With Systematic Errors of Measurement in a Balanced On/Off Study of Social Evaluative Threat

This work constructs a framework for causal inference using blood oxygenation level dependent (BOLD) fMRI time series data, and adjusts for systematic error using measured “noise covariates,” using a linear mixed model to estimate the effects and the systematic error.

Mediation analysis with time varying exposures and mediators

We consider causal mediation analysis when exposures and mediators vary over time. We give non‐parametric identification results, discuss parametric implementation and also provide a weighting

Identification, Inference and Sensitivity Analysis for Causal Mediation Effects

Causal mediation analysis is routinely conducted by applied researchers in a variety of disciplines. The goal of such an analysis is to investigate alternative causal mechanisms by examining the

Parametric Mediational g-Formula Approach to Mediation Analysis with Time-varying Exposures, Mediators, and Confounders

A parametric estimation approach to the mediational g-formula is developed, including a feasible algorithm implemented in a freely available SAS macro, and it is shown that weight change in fact partially conceals the detrimental effects of cigarette smoking on blood pressure.

Analysis of Longitudinal Studies With Repeated Outcome Measures: Adjusting for Time-Dependent Confounding Using Conventional Methods

It is shown how standard regression methods can be used, even in the presence of time‐dependent confounding, to estimate the total effect of an exposure on a subsequent outcome by controlling appropriately for prior exposures, outcomes, and time‐varying covariates.
