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...
significance level意思是显著水平或显著性水平。 显著性水平(Significance Level)详解 定义显著性水平 显著性水平(Significance Level),也被称为显著性或α水平,是统计学中的一个核心概念。它用希腊字母α表示,是一个预设的概率阈值,用于在假设检验中判断一个结果是否足够显著以拒绝原假设...
1. 显著水平(Significance Level)显著水平是在假设检验中预先设定的一个标准,用于判断样本数据所提供的证据是否足够有力,来否定原假设。通常用希腊字母α表示。• 原理:假设检验的基本思想是基于小概率事件原理。在一次试验中,小概率事件几乎是不会发生的。如果在原假设成立的条件下,计算出的统计量对应的概率小于...
Alpha levels can be controlled by youandare related to confidence levels. To get α subtract your confidence levelfrom1. For example,ifyou want to be 95 percent confident that your analysisiscorrect, the alpha level would be 1 – .95 = 5 percent, assuming you had a one tailed test. For...

已知条件“The absolute value of the critical value for the t-statistic is 2.002 at the 5% level of significance”,要求计算95%confidence level 请问在不查阅t分布表的情况下,能否确定这个2.002指的是t0.025的值?因为计算CI需要alpha除以2,但是这个已知条件中无法得知2.002是怎么得出来的?
