confidence level=1-significance level。所以两者是此消彼长的关系。 例如5%的significance level,对应的就是95%的confidence level。正态分布下,此时的关键值(critical value)为±1.96. 1.65或者1.96是critical value,这是查表求得的。 添加评论 0 0 1 回答 0 关注 648 浏览 我要回答 关注问题 相关问题 证书课...
It is recommended that the magnitude of level of confidence be restricted to that of the complement of the level of significance and also that the term level of confidence should be used only in connection with interval estimation.doi:10.1080/00220973.1969.11011150Stallings, William M....
置信区间,就是从未知总体中,只抽取单个样本,估计出总体均值μ所在的一个区间。置信区间,由两部分组成,点估计和上下浮动范围。点估计就是这单次抽样的样本均值,上下浮动的范围是显著水平α所对应的t临界值乘以标准误。 本节课,我们来详细解释一下置信水平这个概念。置信水平的英语叫做Significance Level。置信水平是一...

区间估计(Interval Estimate)和置信水平(Confidence Level) 在点估计的基础上,在一定的置信水平下,给样本统计量加上一个区间范围作为总体参数的取值范围,这个区间叫置信区间(Confidence Interval)。 而置信水平是构造多次置信区间,其中包含了总体参数的置信区间占了多少比例?比如想要估计学生平均成绩,抽取了100个学生样本,...
