3. Tolerance Levels Toleranceis closely related to VIF and represents the proportion of a predictor’s variance that is not explained by other predictors in the model. How to Use Tolerance Levels: Calculate Tolerance for Each Predictor:
aThe indicators of multicollinearity (tolerance, variance inflation factor (VIF), the eigen values and variancedecomposition proportions) were statistically examined and, it is seen that only Cm and a are correlated. multicollinearity (容忍、变化通货膨胀因素(VIF), eigen价值和variancedecomposition比例)显示...
Next we will examine multicollinearity through the Variance Inflation Factor and Tolerance. This can be done by specifying the "vif", "tol", and "collin" options after the model statement: /* Multicollinearity Investigation of VIF and Tolerance */ proc reg data=newYRBS_Total; model SI = Sub...

13 The bottom term of the VIF equation is tolerance, a concept distinct from tolerance intervals. Tolerance is the inverse of VIF. Though much less discussed in literature, it is nevertheless another viable means for calculating multicollinearity.14 The higher the VIF value, the greater degree of...
