STATISTICAL MEDIATION ANALYSIS USING THE SOBEL TEST …
www.eajournals.orgBecause mediation analysis relies on a linear regression analysis, mediating variables follow same set of assumptions required by regression analysis. These assumptions include the following (Author 2016): Levels of Measurement: The independent variable (X) can be either a dummy variable (coded as 0 and 1) or a continuous

Mediation Analysiswith Logistic Regression
web.pdx.eduMediation Analysis with Logistic Regression . Because of the nonlinear nature of logistic regression, the two methods for calculating the indirect effect, ab and c – c’, are no longer equivalent (Winship & Mare, 1983) if either M or Y are binary, particularly with rarer outcomes. The discrepancy between the methods can also vary with the ...
