Rejection Region
释义 Definition
rejection region(统计学)指拒绝域/拒绝区域:在假设检验中,使你拒绝原假设(null hypothesis)的那一部分统计量取值范围;当检验统计量落入该区域时,就做出“拒绝原假设”的决策。(也常与 critical region 近义使用)
发音 Pronunciation (IPA)
/rɪˈdʒɛkʃən ˈriːdʒən/
例句 Examples
The rejection region is where we reject the null hypothesis.
拒绝域是我们拒绝原假设的取值范围。
If the test statistic falls in the rejection region at the 5% significance level, we conclude the result is statistically significant and reject the null hypothesis.
如果检验统计量在 5% 显著性水平下落入拒绝域,我们就认为结果具有统计显著性并拒绝原假设。
词源 Etymology
rejection 来自拉丁语 reiect- / reicere,意为“扔回去、拒绝”;region 来自拉丁语 regio,意为“区域、范围”。合起来在统计语境中引申为“做出拒绝决定的那片范围”,即“拒绝域”。
