| 摘 要： | 根据零膨胀计数数据的特点,将Bootstrap统计技术运用到零膨胀泊松回归模型的置信区间计算及参数假设检验。通过计算机模拟,得到：第一,当样本量较小时,Bootstrap对参数估计进行假设检验的结果更为保守;第二,Bootstrap的学生氏置信区间优于零膨胀泊松回归模型的区间估计。

| Abstract: | Bootstrap is applied to the Zero Inflated Poisson regression model in confidence intervals and hypothesis testing with Zero Inflated data. The outcomes of the hypothesis testing from the Bootstrap method are more conservative than the ones from the ZIP regression model when sample sizes are small. Also the confidence intervals from the Bootstrap method are more accurate than the ones from the ZIP regression model. |
