One approach is to remove one of the highly correlated variables, especially if it does not add substantial theoretical value. Addressing High VIF When encountering high VIF values, analysts have several options to improve model stability.
Process Repeated for VIF Scores and Strategic Variable Management
Careful consideration of the underlying theory remains crucial when making these adjustments. For a given variable, you regress it against all other predictors in the equation and compute the R-squared value from that regression.
Document decisions regarding variable retention or removal, and consider replicating analyses with and without high-VIF variables to assess robustness. This disciplined approach ensures that conclusions drawn from regression models are both statistically sound and conceptually meaningful.
Repeating the VIF Analysis for Consistent Results
Practical Examples of Interpretation In practical terms, imagine a real estate model using predictors such as square footage, number of rooms, and property age. 5, it suggests redundancy that might obscure the true impact of each variable.
