The best way to examine repeatability is to take repeated measurements on a series of subjects. The table shows paired data for PEFR. We can then plot a figure similar to fig 2,
showing differences against mean for each subject. If the differences are related to the mean,we can apply a log transformation. We then calculate the mean and standard deviation of the differences as before. The mean difference should here be zero since the same method was used. (If the mean difference is significantly different from zero, we will not be able to use
the data to assess repeatability because either knowledge of the first measurement is affecting the second or the process of measurement is altering the quantity.) We expect 95% of
differences to be less than two standard deviations. This is the definition of a repeatability coefficient adopted by the British Standards Institution. 7 If we can assume the main difference to be zero this coefficient is very simple to estimate: we squar

此翻译请楼主绝对放心，楼主也是8级大侠，定能明鉴
The best way to examine repeatability is to take repeated measurements on a series of subjects. The table shows paired data for PEFR. 检查重复性的最好方法是对一系列主体进行重复的测量。表格列出了PEFR（呼气流速变化率）的成对数据。We can then plot a figure similar to fig 2, showing differences against mean for each subject.于是我们就能绘出一幅类似于图2的图，显示每一主体相对于平均值的差别。If the differences are related to the mean,we can apply a log transformation.如果这些差别与平均值有关，我们可以实施对数变换。 We then calculate the mean and standard deviation of the differences as before. 然后我们就可以像前面一样计算平均值和这些差别的标准偏差。The mean difference should here be zero since the same method was used. 由于采用了相同的方法，所以这里的平均差别应该为零。(If the mean difference is significantly different from zero, we will not be able to use the data to assess repeatability because either knowledge of the first measurement is affecting the second or the process of measurement is altering the quantity.) （如果平均差别明显不等于零，我们就不能利用这些数据来评估重复性，因为对第一次测量的了解正影响着第二次测量，而且测量的过程正在使数量发生改变。）We expect 95% of
