The VIF of variable (i) can be found as the reciprocal of (1-R_squared(i)), where R_squared(i) is the coefficient of determination for a model in which X(i) is predicted from the remaining X's.

Haitham Hmoud Alshibly

VIF is a measure of collinearity between two independent variables or

multicollinearity among three or more independent variables. It is the proportion of variance in one independent variable that is not explained by the remaining independent variables.. VIF values of just over 1.0 are desirable, with the floor VIF value being 1.0. A VIF value of 1.007 would be considered very good and indicative of no collinearity.
