Variance inflation factor, Advanced Statistics

VIF is the abbreviation of variance inflation factor which is a measure of the amount of multicollinearity that exists in a set of multiple regression variables.

*The VIF value being above the upper limit of 10 suggest that there is severe multicollinearity

The VIF Equation:

 The VIF value is below the upper limit of 10 (1.353 < 10) therefore it reveals that Wfood is not strongly correlated with the other independent variables and there is no multicollinearity.
