- Moderation is often tested using multiple regression analysis by including an interaction term between the independent variable and the moderator. The basic equation is: Y=β0+β1X+β2M+β3 (X×M)+εY = beta_0 + beta_1X + beta_2M + beta_3 (X imes M) + varepsilon where: ε is the error term.researchmethodology.org/moderating-variable/
