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:
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...
Tolerance:Tolerance is simply the reciprocal of the VIF: Tolerancei= 1 / VIFi Values of tolerance close to 0 indicate high multicollinearity. A common cutoff is 0.1, but again, the appropriate threshold depends on the context. Some other Detection Methods 4.Eigenvalues and Condition Index:This ...
Here is part of the advice I gave on Dec. 10, and others had additional suggestions: Some things you could try that I am aware of: * Use the -collin- procedure (use -findit collin- to get it). Typical format is -collin x1 x2 x3-. It'll give you vif, tolerance, some other s...
Or maybe somebody has a vif2 command that I haven't found yet? Some things you could try that I am aware of: * Use the collin procedure (use Findit collin to get it). Typical format is collin x1 x2 x3. It'll give you vif, tolerance, some other stats. Since Y is not included...

(1-R²) is also known as thetolerance. You repeat the process above for the other features and calculate the VIF for each features: x₂ ~ x₁ + x₃ + x₄ # regress x₂ against the rest of the features x₃ ~ x₁ + x₂ + x₄ # regress x₃ against the rest...

I would appreciate to learn any potential reasons of why condition number indicates serious multicollinearity (over 30), while individual and mean VIFs indicate no evidence. Thank you, Yujin SQRT Eigenval Cond.Index Var VIF VIF Tolerance 1 5.618 1.000 v1 1.04 1.02 0.965 2 1.701 1.818 v2 1.21...
