Rule of thumb correlation

WebbThe 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 WebbHenson and Roberts5 pointed out that a correlation matrix is most popular among investigators. Tabachnick and Fidell10 recommended inspecting the correlation matrix (often termed Factorability of R) for correlation coefficients over 0.30. Hair et al. (1995) categorised these loadings using another rule of thumb as ±0.30=minimal,
