In statistics, a mediation model seeks to identify and explain the mechanism or process that underlies an observed relationship between an independent variable and a dependent variable via the inclusion of a third hypothetical variable, known as a mediator ...
Moderated Mediation Model with a 3 level Multi-categorical Antecedent Variable. Preacher, Rucker and Hayes also discuss an extension of simple slopes analysis for moderated mediation.
