UPCOMING WEBINAR: The Roadmap for Market Researchers in the Age of AI This article describes how to compute the variance inflation factors (VIF) of linear models and generalized variance-inflation factors (GVIF) for generalized linear models to diagnose multicollinearity.
Requirements
- A Regression output for one of the following types of regressions:
- Linear
- Binary Logit
- Ordered Logit
- Poisson
- Quasi-Poisson
- NBD
Note: This feature is not compatible with multinomial logit regressions.
Method
- Select the Regression output.
- Go to the object inspector > Data > Diagnostics >Multicollinearity Table (VIF).
