This workflow demonstrates how to use the the Variance Inflation Factors macro alongside a Logistic Regression tool. Variance Inflation Factors produces a coefficient summary report that includes either the variance inflation factor (or VIF) or a generalized version of the VIF (GVIF) for all variables except the model intercept (which always has a VIF or GVIF that equals one). The tool produces VIF values if none of the predictors are categorical variables with more than two levels, and produces GVIF values otherwise. The "standardized" (G)VIF values correspond to (G)VIF^[1/(2*DF)]. This tool can be applied to models created by the Linear, Logistic, Count, and Gamma regression tools in cases where the model is estimated using open source R routines, but not Revo ScaleR methods, since the Revo ScaleR model objects do not contain the information needed to calculate (G)VIFs.
