Fig. 4

Mean of the standardized differences of the probability of being an excessive zero and the probability of being a sampling zero when data are simulated from a ZINB model of sample size n=300. In the left panel, the covariate is a binary variable from a Bernoulli random variable with probability parameter 0.5. In the right panel, the covariate is a continuous variable from a standard normal distribution
