摘　　要：目的　为探索更加完善的 2×k表多重比较 χ2 检验统计分析方法。方法　本研究使用蒙特卡洛法在计算机上产生二项分类的样本数据 ,按照 χ2 检验理论计算 χ2 值 ,根据 2×k表多重比较 χ2 检验界值的准确性和稳定性 ,确定总体率、样本含量、抽样次数的数值。结果　在反复、细致、大量的运算分析之后 ,研制出 2×k表多重比较 χ2 检验界值。结论　经合理分析表明 ,本界值准确性高、稳定性好。Objective To approach a more complete statistical method of χ 2-test on the multiple comparison in 2×k table.Methods The study used Mote Carlo method to create binomial sample data on computer.The χ 2-values were calculated according to χ 2-test theory and the values of population rate,sample size and sampling times were determined in accordance with the accuracy and stability of χ 2-values on the multiple comparison in 2×k table.Results After enormous calculations with repeated and detailed analyses the χ 2-test Critical values on multiple comparison in 2×k table were created.Conclusion Reasonable analyses showed that the critical values have high accuracy and stability.
