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 explore a more sophisticated 2×k table multiple comparison χ2 test statistical analysis method. Methods This study used Monte Carlo method to generate binomial sample data on a computer. The χ2 value was calculated according to χ2 test theory. The overall rate and sample were determined according to the accuracy and stability of the 2×k table multiple comparison χ2 test boundary value. Content, number of sampling times. Results After repeated, meticulous and extensive computational analysis, a 2×k table multiple comparison χ2 test boundary was developed. Conclusions Reasonable analysis shows that the bound value has high accuracy and good stability.
