Careful consideration of the underlying theory remains crucial when making these adjustments. Addressing High VIF When encountering high VIF values, analysts have several options to improve model stability.
Effective Variable Selection Using VIF Scores for Model Stability
One approach is to remove one of the highly correlated variables, especially if it does not add substantial theoretical value. Analysts should complement VIF with other diagnostics and subject-matter expertise.
It quantifies how much the variance of a regression coefficient is inflated due to linear relationships with other predictors. Always visualize correlations with heatmaps or scatterplots to understand relationships before interpreting VIF scores.
Effective Variable Selection Strategies Using VIF Scores
Calculating VIF The calculation of VIF involves running separate regression models for each predictor. Document decisions regarding variable retention or removal, and consider replicating analyses with and without high-VIF variables to assess robustness.
