10.7 - Detecting Multicollinearity Using Variance Inflation …
WebThe general rule of thumb is that VIFs exceeding 4 warrant further investigation, while VIFs exceeding 10 are signs of serious multicollinearity requiring correction. Steps to calculate VIF: Regress the k t h predictor on rest of the predictors in the model. Compute the R k 2. V I F = 1 1 − R k 2 = 1 T o l e r a n c e. WebMar 14, 2024 · One method to detect multicollinearity is to calculate the variance inflation factor (VIF) for each independent variable, and a VIF value greater than 1.5 indicates multicollinearity.
