Enter the R-squared (coefficient of determination) value of the data set into the calculator to determine the variance inflation factor.
Variance Inflation Factor Formula
The following formula is used to calculate a variance inflation factor.
VIF = 1 / (1-R2 )
- Where VIF is the variance inflation factor
- R2 is the coefficient of determination of the regression equation
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.
Variance Inflation Factor Example
How to calculate variance of inflation?
- First, determine the coefficient of determination.
Calculate the coefficient of determination of the data set or model.
- Next, calculate the VIF.
Calculate the variance inflation factor using the equation above.
In statistics, VIF stands for the variance inflation factor.
