Multiplicative Interactions
Multiplicative Interactions
Interaction models have been popular in the social sciences. However, recent reviews [1, 2, 3] have revealed serious problems with regard to their construction and interpretation. In particular, the exclusion of constituent variables has led to the specification of incorrect models, in the sense of a mismatch between model form and the objective of the researcher formulating the model. This Demonstration illustrates the consequences of not including all constituent variables for the estimation of marginal effects.
