“置信界限”常见的英语表达是 confidence limit(单数形式,指一个界限值)或 confidence limits(复数形式,指上下两个界限值) 。
在统计学语境中,confidence limit/limits 常与 confidence interval(置信区间)相关联,置信区间由上下两个置信界限构成,用于表示参数估计的可靠范围。例如:
The 95% confidence limits for the mean are calculated based on the sample data.(根据样本数据计算出了均值的95%置信界限。)
We are 95% confident that the true value lies within these confidence limits.(我们有95%的把握认为真实值位于这些置信界限之内 。)
