- Variance inflation factor - Wikipedia
In statistics, the variance inflation factor (VIF) is the ratio (quotient) of the variance of a parameter estimate when fitting a full model that includes other parameters to the variance of the parameter estimate if the model is fit with only the parameter on its own [1]

Variance Inflation Factors (VIFs) measure the correlation among independent variables in least squares regression models Statisticians refer to this type of correlation as multicollinearity Excessive multicollinearity can cause problems for regression models
- 10. 7 - Detecting Multicollinearity Using Variance Inflation Factors
As the name suggests, a variance inflation factor (VIF) quantifies how much the variance is inflated But what variance? Recall that we learned previously that the standard errors — and hence the variances — of the estimated coefficients are inflated when multicollinearity exists
