Relative significance of exogenous variables
Posted: Thu Jan 17, 2019 9:14 am
Hello,
Suppose there are five independent variables and one dependent variable in a model. All the five independent variables are hypothesized to have direct influence on the dependent variable. However, one of the independent variables has also been hypothesized to be a mediator between another independent variable and the dependent one. Now, we want to investigate the relative influence of the independent variables on the dependent variable.
Q) Should the structural model be tested without mediation? or with mediation? (objective is to check relative influence of the independent variables only); If with mediation is required, then should the the relative influence be checked on the basis of path coefficients (direct effect)? or on the basis of total effects?
Thanks
