目的 为探索更加完善的多个样本率两两比较的统计分析方法。方法 应用蒙特卡洛法在计算机上产生二项分类的样本数据。在反复分析运算之后 ,确定正式实验条件为 :总体率为 0 2 5 ,样本含量为 15 0 ,样本个数为 3、4、5、6、7、8、9、10 ,抽样次数为 10 0 0 0 0 0 ,概率为 0 90、0 75、0 5 0、0 40、0 30、0 2 0、0 10、0 0 5、0 0 2 5、0 0 1、0 0 0 5。结果 在大量正式运算之后 ,研制出多个样本率两两比较 χ2 检验界值。结论 合理的分析表明 ,本界值准确性高。
Objective To explore a more comprehensive statistical analysis method for comparing multiple sample rates. Methods The Monte Carlo method was used to generate binomial sample data on the computer. After repeated analysis and calculation, determine the formal experimental conditions as follows: the overall rate is 0 2 5, the sample size is 15 0, the number of samples is 3, 4, 5, 6, 7, 8, 9, 10, and the sampling frequency is 10 0 0 0 0 0, the probability is 0 90, 0 75, 0 5 0, 0 40, 0 30, 0 2 0, 0 10, 0 0 5, 0 0 2 5, 0 0 1, 0 0 0 5. Results After a large number of formal operations, multiple sample rates were developed to compare χ2 test cutoffs. Conclusion Rational analysis shows that the accuracy of this bound is high.
