In statistics, the variance inflation factor (VIF) is a method of detecting the severity of multicollinearity.Hair JF, Anderson R, Tatham RL, Black WC: "Multivariate Data Analysis". Prentice Hall: Upper Saddle River, N.J. 2006. In statistics, the variance inflation factor (VIF) is the ratio of variance in a model with multiple terms, divided by the variance of a model with one term alone.
