Researchers in psychology and other social sciences are often interested in performing mediation analysis to explain the relationship between an independent variable (X) and dependent variable (Y) in terms of a third hypothesized process or mediating variable (M). In R, this kind of analysis may be conducted in two ways: Baron & Kenny's (1986) 4-step indirect effect method and the more recent mediation package (Tingley, Yamamoto, Hirose, Keele, & Imai, 2014). & Shelvin, M.

Once again, this highlights the fact that if we are interested in mediation analysis, then we must control for mediator-outcome confounders. I describe a test of linear moderated mediation in path analysis based on an interval estimate of the parameter of a function linking the indirect effect to values of a moderator—a parameter that I call the index of moderated mediation.
