The prior weights in the mediator and outcome models are taken as sampling weights and the estimated effects will be weighted averages when non-NULL weights are. First, we have the "what question": for example, does drinking as opposed to not drinking influence a dependent variable such as mood? Secondly, the "how question": does a mediator sit between an independent and dependent variable. Structural Equation Modeling is one of the most popular and flexible modeling approaches in the social and health sciences. Mediation and moderation can co-occur in statistical models.
