Variance inflation factor (VIF) quantifies how much the variance is inflated due to collinearity of regressor matrix columns. i_th entry in the output vector is the variance inflation factor for the i_th predictor, which indicates how much the variance of the i_th predictor is inflated due to collinearity.
