置信区间 Confidence interval

(重定向自Confidence level)

在统计学中,一个概率样本的置信区间Confidence interval)是对这个样本的某个总体参数的区间估计。置信区间展现的是这个参数的真实值有一定概率落在测量结果的周围的程度。置信区间给出的是被测量参数的测量值的可信程度,即前面所要求的“一定概率”。这个概率被称为置信水平举例来说,如果在一次大选中某人的支持率为55%,而置信水平0.95上的置信区间是(50%,60%),那幺他的真实支持率有百分之九十五的机率落在百分之五十和百分之六十之间,因此他的真实支持率不足50%的可能性小于百分之2.5(假设分布是对称的)。

Confidence interval 置信区间

(重定向自Confidence level)
In this bar chart, the top ends of the bars indicate observation means and the red line segments represent the confidence intervals surrounding them. Although the bars are shown as symmetric in this chart, they do not have to be symmetric.
The blue vertical line segments represent 50 realizations of a confidence interval for the population mean μ, represented as a red horizontal dashed line; note that some confidence intervals do not contain the population mean, as expected.

In statistics, a confidence interval (CI) is a type of interval estimate of a population parameter. It is an observed interval (i.e., it is calculated from the observations), in principle different from sample to sample, that frequently includes the value of an unobservable parameter of interest if the experiment is repeated. How frequently the observed interval contains the parameter is determined by the confidence level or confidence coefficient. More specifically, the meaning of the term "confidence level" is that, if CI are constructed across many separate data analyses of replicated (and possibly different) experiments, the proportion of such intervals that contain the true value of the parameter will match the given confidence level. Whereas two-sided confidence limits form a confidence interval, their one-sided counterparts are referred to as lower/upper confidence bounds (or limits).
