Maximum likelihood estimates of beta-Poisson model parameters by dataset, 95% confidence intervals in parentheses.

Values of 0.00 in the confidence intervals for Φ represent small non-zero values rounded for display purposes; values of 0 in the MLE or confidence intervals for ν represent “true” zeros corresponding to fits where the MLE is at the negative binomial limit.

Φ的置信区间中取值为0.00的数值，实为为便于展示而经四舍五入处理的极小非零值；ν的最大似然估计（Maximum Likelihood Estimation, MLE）结果或其置信区间中取值为0的数值，则代表“真实零值”，对应于最大似然估计处于负二项分布边界的拟合场景。
