Simulation results for the simulation setting #1 (true model: HNB model with a single continuous covariate generated from a standard normal distribution). Evaluation criteria include \(\bar {\Delta }\)AIC (mean difference in AICs of the ZINB and HNB models); %ΔAIC>4 (percentage of the differences in AICs between the ZINB and HNB models that are above 4; the percentage of Vuong’s test p-value <5% and the percentage of the SW normality test of the RQRs for the ZINB model <5%
