QIC calculates the value of the quasi-likelihood under the independence model criterion for Generalized Estimating Equations. The QIC criterion is actually a generalization of the AIC criterion in the statistical inference of parameters in the longitudinal data analysis framework.
a value indicating how well the model fits
