Robustness Testing: Replacing Explanatory Variables and Regression Analysis

Substitute independent variables and perform regression analysis to conduct a robustness examination. This process involves replacing the original explanatory variables with alternative measures or variables that capture similar concepts. By running the regression model with these substituted variables, researchers can assess the stability and reliability of the original model's findings. If the results remain consistent despite the changes in explanatory variables, it strengthens the robustness of the model.
