同学你好, 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...
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....

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,这些样本构造了100个置信区间,有95个包含了总体平均分真实值,这时候置信水平就是95%,显著性水平(Significance Level) 则是0.05。 常用的置信水平包括90%,95%,99%。这里要注意,对“在95%的置...
