置信区间;信赖区间;可靠区间
1. a group of continuous or discrete adjacent values that is used to estimate a statistical parameter (such as a mean or variance) and that tends to include the true value of the parameter a predetermined proportion of the time if the process of finding the group of values is repeated a number of times
see the confidence intervals section in the article supplement for more discussion.
补充资料的confidence intervals一节详细讨论了这个问题。
confidence intervals are the most prevalent form of interval estimation.
区间是所确定的估计值的取值范围。

historically, confidence intervals could only be easily calculated for a few common pdfs (such as the gaussian) and simple statistics (such as the mean).
在以前,只能针对一些常见的pdf(比如gaussian)和简单的统计数据(比如平均值)计算置信区间。

the confidence intervals for the means are always so tight — typical width is ~1000 times smaller than the mean — that they will not show up on these graphs.
(平均值的置信区间都很窄,宽度通常小于平均值的千分之一,所以没有在图上显示出来)。
