    Goodness of fit (QIC) in Generalized Estimating Equations (GEE)

    Hi, I have a question concerning goodness of fit which is measured as QIC in the GEE analysis: In general I learned that if QIC decreases the change in the model was for the better. => Decrease in QIC = Good However, I am trying to add new model terms and for all of them QIC...

    Are nearly identical QIC scores considered equal?

    I am using QIC (Quasilikelihood under the Independence model Criterion) to evaluate different correlation matricies in a GEE (using identical covariates in all models). I have 2 scores: 474.381 and 474.375. QIC is in the smaller is better format, but with such minimal differences at what...
