Chapter 1: Linear regression analysis view examples. Serial mediation is when an IV predicts a mediator (M1) which subsequently predicts another mediator (M2), which then predicts a DV. Sensitivity analysis allows the analyst to state how an estimated quantity would change for diﬀerent degrees of violation of the key identiﬁcation assumption (Rosenbaum 2002). moderation and moderated mediation models, including those corresponding in type to the 76 configuration listed and index by Andrew Hayes in the documentation for his SPSS PROCESS macro.
