[translate] anull hypothesis and alternative hypothesis 无效假设和假设[translate]
假设检验中,有一对假设: ① 原假设H0。英语中称为「Null Hypothesis」,Null是「零」的意思,所以「原假设」也是「零假设」。万事皆零,「零」是事物的本来面貌。 ② 备择假设H1。英语称为「Alternative Hypothesis」。 关于这一对假设,需要知道: ① 原假设H0虽是事物的本来面貌,但确是研究者想收集证据予以反对...

在假设检验中,零假设(Null Hypothesis)是统计检测时的一类假设。零假设的内容一般是希望证明其错误的假设。与零假设相对立的就是操作性对立假设又称为备择假设(Alternative Hypothesis)即不希望看到的另一种可能。定义 从数学上来看,零假设和备择假设的地位是相等的,但是在统计学的实际运用中,常常需要强调一类...
假设性检验问题,检验的是整体的统计量。定义null hypothesis和alternative hypothesis,对于假设性检验根据简介中的方法会有两种结论,注意在null hypothesis里面,必须是等号 拒绝 ,接受 :这表明我们有足够的证据证明 是正确的 无法拒绝 ,拒绝 :之所以无法说接受 ...
The Null hypothesis is rejected and the likelihood of the alternative hypothesis as significant is accepted. 零假设被拒绝,而备择假设显著的可能性则被接受。 ParaCrawl Corpus It is the probability of rejecting the null hypothesis when it is false. 它是当原假设为假时拒绝原假设的概率。 ParaCr...
Alternative Hypothesis: two tailed 实例: one tailed 实例: 评判标准: Type I and Type II Errors: Significance Level 所以需要balancing In otherwords, if we do not reject the null hypothesis, we conclude only that the data do notprovide sufficient evidence to support the alternative hypothesis; we...
Null hypothesis: “xis equal toy.” Alternative hypothesis “xis not equal toy.” Null hypothesis: “xis at leasty.” Alternative hypothesis “xis less thany.” Null hypothesis: “xis at mosty.” Alternative hypothesis “xis greater thany.”...
