To quantify the effect of a moderating variable in multiple regression analyses, regressing random variable Y on X, an additional term is added to the model. This term is the interaction between X and the proposed moderating variable. [1] Thus, for a response Y and two variables x 1 and moderating variable x 2,:
A moderator variable that increases the predictive validity of another variable is known as a suppression variable. When a third variable (a moderator variable here) is added, the magnitude of a relationship becomes larger between an independent variable and a dependent variable. This would indicate suppression.
In statistics, moderation and mediation can occur together in the same model. [1] Moderated mediation, also known as conditional indirect effects, [2] occurs when the treatment effect of an independent variable A on an outcome variable C via a mediator variable B differs depending on levels of a moderator variable D.

Meta CEO Mark Zuckerberg on Tuesday said the social media company is ending its fact-checking program and replacing it with a community-driven system similar to that of Elon Musk's X.
In a model including mediating and moderating variables, it is the combination of direct and indirect effects that makes up the total effect of an independent variable on a dependent variable. Thus, "if an indirect effect does not receive proper attention, the relationship between two variables of concern may not be fully considered" (Raykov ...
