VarianceInflation

As of Version 7.0, VarianceInflation has been renamed to "VarianceInflationFactors" and has become a property of LinearModelFit.

VarianceInflation

is a possible value for the RegressionReport option for Regress and DesignedRegress that represents variance inflation factors.

Details and Options

  • To use VarianceInflation, you first need to load the Regression Common Functions Package. You can do this by using Needs["LinearRegression`"], which will automatically load the Regression Common Functions Package, or you can load the package directly by using Needs["RegressionCommon`"].
  • VarianceInflation gives a list of inflation factors for the estimated parameters.
  • A value greater than 1/(1-RSquared) indicates multi‐collinearity with other basis functions.
