摘要 对配对设计试验,基于Tango(1998)得分统计量导出了检验2个比值非零差的2种近似样本量公式.由这些公式得到的样本量能达到预先指定的功效和控制置信区间的宽度.一个实例和一些经验结果验证了方法的有效性. Two approximate sample size formulae are proposed for testing the null hypothesis of nonzero rate difference of two proportions in matchedpair design based onTango's score test statistic.The formulae can be used to produce sample size estimates that guarantees a prespecified power of a hypothesis test at a certain significance level and controls the width of a confidence interval with a certain confidence level.Our empirical studies confirm that the proposed sample size formulae perform satisfactorily.A real example is used to illustrate our methods.
