摘要
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 The study designed to approach a more complete statistical method of the multiple comparison among several sample rates obtained from binomial distribution data with Mote Carlo method on a computer.Methods After calculations and analyses,the formal experimental factors were determined.The population rate:0 25;the sample numbers:3,4,5,6,7,8,9,10;the sampling times:1000000;the probabilities:0 90,0 75,0 50,0 40,0 30,0 20,0 10,0 05,0 025,0 01,0 005.Result After a large number of calculations the χ 2—test critical values for the multiple comparison among several sample rates were brought out.Conclusion Reasonable analyses show that the critical values have high accuracy.
