Growth Estimators and Confidence Intervals for the Mean of Negative Binomial Random Variables with Unknown Dispersion

Figure 4

An example of misspecified growth. Despite low dispersion, zeros were aggressively removed at a rate of one for every 5 data points up to a maximum of 15. The GBA and GBR methods’ coverage probabilities dip significantly until this maximum value is reached and then rebound toward the Normal approximation.
