Simulation results for the simulation setting #1 (true model: HNB 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 ZINB and HNB models); %ΔAIC>4 (percentage of the differences in AICs between the ZINB and HNB models that are above 4; percentage of Vuong’s test p-value <5% and percentage of the SW normality test of the RQRs for the ZINB model <5%
