The variance inflation factor (VIF) and tolerance are two closely related statistics for diagnosing collinearity in multiple regression. They are based on the R-squared value obtained by regressing a predictor on all of the other predictors in the analysis. Tolerance is the reciprocal of VIF.
How do you interpret VIF and tolerance?
Generally, a VIF above 4 or tolerance below 0.25 indicates that multicollinearity might exist, and further investigation is required. When VIF is higher than 10 or tolerance is lower than 0.1, there is significant multicollinearity that needs to be corrected.
What is tolerance in multicollinearity?
Tolerance is used in applied regression analysis to assess levels of multicollinearity. Tolerance measures for how much beta coefficients are affected by the presence of other predictor variables in a model. Smaller values of tolerance denote higher levels of multicollinearity.
