## Variance Inflation Factor Formula

The following formula is used to calculate a variance inflation factor.

VIF = 1 / (1-R^2 )

- Where VIF is the variance inflation factor
- R2 is the coefficient of determination of the regression equation

To calculate a variance inflation factor, divide 1 by 1 minus the coefficient of determination.

## Variance of Inflation Definition

A variance of inflation is defined as the quotient of the variance in a model with multiple terms by the variance in a model with one term alone.
