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.
Interaction effect of education and ideology on concern about sea level rise. In statistics, an interaction may arise when considering the relationship among three or more variables, and describes a situation in which the effect of one causal variable on an outcome depends on the state of a second causal variable (that is, when effects of the two causes are not additive).
Variable APY. APYs can be fixed or variable , depending on the type of deposit account. Fixed rates don't fluctuate when, say, the Fed rate changes, while variable APYs do.

Area c is the variance that the independent variable and the dependent variable have in common with the mediator, and this is the indirect effect. [ citation needed ] [ clarification needed ] Area c corresponds to the product of coefficients ( αβ ) and to ( τ − τ ' ).
