Introduction to mediation analysis with structural equation modeling
In mediation, we consider an intermediate variable, called the mediator, that helps explain how or why an independent variable influences an outcome. In the context of a treatment study, it is often of great interest to identify and study the mechanisms by which an intervention achieves its effect. By investigating mediational processes that clarify how the treatment achieves the study outcome,...
متن کاملmediation: R Package for Causal Mediation Analysis
In this paper, we describe the R package mediation for conducting causal mediation analysis in applied empirical research. In many scientific disciplines, the goal of researchers is not only estimating causal effects of a treatment but also understanding the process in which the treatment causally affects the outcome. Causal mediation analysis is frequently used to assess potential causal mecha...
متن کاملCommentary: Causal Effects in Mediation Modeling: An Introduction with Applications to Latent Variables
Causal mediation1 is an increasingly popular analysis, as recently described by Muthén and Asparouhov (2015, M&A)2. We suggest a simplified notation for causal mediation effects, iT/iP=BK and dT/dP, provide a graphical view of potential outcomes (PO) and expand the M&A approach by using VanderWeele’s (2014) mediation decomposition. An intuitive way to label and see causal in/direct effects is t...

متن کاملMirror Mediation
I show that the effective action of string compactifications has a structure that can naturally solve the supersymmetric flavour and CP problems. At leading order in the gs and α ′ expansions, the hidden sector factorises. The moduli space splits into two mirror parts that depend on Kähler and complex structure moduli. Holomorphy implies the flavour structure of the Yukawa couplings arises in o...
