英语翻译
The limits of agreement are only estimates of the values which apply to the whole population.A second sample would give different limits.We might sometimes wish to use standard errors and confidence intervals to see how precise our estimates are,provided the differences follow a distribution which is approximately Normal.The standard error of d is s2 / n ,where n is the sample size,and the standard error of d - 2s and d + 2s is about 3s2 / n .
95% confidence intervals can be calculated by finding the appropriate point of the t distribution with n -1 degrees of freedom,on most tables the columns marked 5% or 0.05,5 and then the confidence interval will be from the observed value minus t standard errors to the observed value plus t standard errors.

一致性范围是唯一适用于总体的估值.不同的样本有不同的范围.假设偏差是近似遵循正态分布的,我们有时可能希望用标准差和置信区间来衡量我们的估值的准确.
The standard error of d is s2 / n , where n is the sample size, and the standard error of d - 2s and d + 2s is about 3s2 / n . 95% confidence intervals can be calculated by finding the appropriate point of the t distribution with n -1 degrees of freedom, on most tables the columns marked 5% or 0.05,5 and then the confidence interval will be from the observed value minus t standard errors to the observed value plus t standard errors.
d的标准差是s2 / n,其中n是样本容量.d-2s和d+2s的标准差大约是3s2 / n.置信概率95%时的置信区间可以通过寻找适当的N-1自由度t分布中的近似点来计算,在大多数图表中纵列标记为5%或者0.05,那么置信区间就是从(测量值-t标准差)到(测量值+t标准差)
