Which variance inflation factor should I be using: $\\text{GVIF}
WebVariables which require more than 1 coefficient and thus more than 1 degree of freedom are typically evaluated using the GVIF. For one-coefficient terms VIF equals GVIF. Thus, you may apply standard rules of thumb on whether collinearity may be a problem, such as a 3, 5 or 10 threshold.

We therefore report it like just a basic ANOVA too. So we'll write something like “Levene’s test showed that the variances for body fat percentage in week 20 were not equal, F(2,77) = 4.58, p = .013.”. child hunger in maryland
