中文摘要:针对已存在关于零膨胀的R检验、C检验、Score检验、卡方检验、似然比检验、Wald检验和基于置信区间检验,通过Monte Carlo模拟分析方法,在功效和犯第一类错误比例的意义下,在不同零膨胀程度、不同均值和不同样本量下对上述检验作比较研究.得到了不同条件下7种检验方法的优良性,并结合理论对7种检验方法进行分析. |
中文关键词:零膨胀 模拟 检验功效 第一类错误 |

Abstract:R test, C test, Score test, chi-square test, likelihood ratio test,Wald test and confidence interval test were compared based on numerical simulation method.We compared the test of power and type one error, in different zero-inflated, different mean values and different sample sizes. Finally, we got the superiority of seven test and gave suggestions for selecting test in different conditions. |
keywords:zero-inflated simulation power of test type one error |
