Simple mediation model. The independent variable causes the mediator variable; the mediator variable causes the dependent variable. In statistics, a mediation model seeks to identify and explain the mechanism or process that underlies an observed relationship between an independent variable and a dependent variable via the inclusion of a third hypothetical variable, known as a mediator ...
Moderated Mediation Model with a 3 level Multi-categorical Antecedent Variable. Preacher, Rucker and Hayes also discuss an extension of simple slopes analysis for moderated mediation. Under this approach, one must choose a limited number of key conditional values of the moderator that will be examined.
The Sobel test is basically a specialized t test that provides a method to determine whether the reduction in the effect of the independent variable, after including the mediator in the model, is a significant reduction and therefore whether the mediation effect is statistically significant.
Mediation is a negotiation facilitated by a third-party neutral. It is a structured, interactive process where an independent third party, the mediator, assists ...
Moderation analysis in the behavioral sciences involves the use of linear multiple regression analysis or causal modelling. [1] 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.
The problem of mediation in Marxism is also referred to as the problem of determination, or namely how social actors navigate the social structures that bind them. For Marx, the primary form of mediation is labor, which forms a dialectical relationship between a worker's body and nature. Labor thus mediates between humans and the natural world.

Dummy variables are commonly used in regression analysis to represent categorical variables that have more than two levels, such as education level or occupation. In this case, multiple dummy variables would be created to represent each level of the variable, and only one dummy variable would take on a value of 1 for each observation.
