This selection criterion is designed as approximately unbiased estimates of the expected Kullback-Leibler information for nonparametric functions under quasi-likelihood models. The finite sample performance of the AICC is demonstrated via Monte Carlo simulations for nonparametric logistic and Poisson regression models. The results show that AICC is better than both the Akaike information criterion and the generalized cross-validation critserion.Akaike information criterionGeneralized cross-validationLocal quasi-likelihoodSmoothing parameter estimatorjournal article10.1080/10485250600867182
