Simulation results for the simulation setting #2 (true model: ZINB model with a single binary covariate generated from a Bernoulli distribution with probability parameter 0.5). Evaluation criteria include \(\bar {\Delta }\)AIC (mean difference in AICs of the HNB and ZINB models); %ΔAIC>4 (percentage of the differences in AICs between the HNB and ZINB 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 HNB model <5%
