Mediation Analysis: Expanding From One Mediator to Multiple Mediators

Mediation analysis is the process of determining whether or not variables acting as an in-between step, called mediators, are present when looking at the relationship between an independent variable X and a dependent variable Y. An educational study was proposed to analyze the effect of different classroom environments on students performance. This study also measured if the student is on-task ...

Accuracy Mediation within a Spatial Wrapper-Mediator System

Query evaluation strategies in traditional databases do not consider possible data inaccuracy and vagueness of predicates. However, measurement considerations and data quality are inherent components of geographic information. The purpose of this work is to explore query evaluation in distributed spatial information mediation system that takes into account different accuracy characteristics of ...

Sharp sensitivity bounds for mediation under unmeasured mediator-outcome confounding

It is often of interest to decompose the total effect of an exposure into a component that acts on the outcome through some mediator and a component that acts independently through other pathways. Said another way, we are interested in the direct and indirect effects of the exposure on the outcome. Even if the exposure is randomly assigned, it is often infeasible to randomize the mediator, leav...

Mediation Formula for a Binary Outcome and a Time-Varying Exposure and Mediator, Accounting for Possible Exposure-Mediator Interaction.

Valeri and VanderWeele [1] used the counterfactual framework to extend formulas from Baron and Kenny [2] to account for exposure-mediator interaction in mediation analysis. The results are also extended to the case when the outcome is binary. VanderWeele and Tchetgen Tchetgen [3] identified the randomized interventional analogues of the natural direct and indirect effects in longitudinal settin...
