Hypothesis Testing (P-value approach) P-value代表的是一个概率,它假设null hypothesis是True的情况下,在alternative hypothesis方向上出现一个比我们sample data的test statistic更极端的test statistic的概率。如果P-value是小于(或等于)α,那么null hypothesis is rejected. 如果P-value是大于α,那么null hypothesis ...
9.2 Critical-Value Approach to Hypothesis Testing example: 对于mean 值 275 的假设: 有一个关于sample mean的distribution: 已知population 标准差和sample size=25的情况下: 标准型Z为: 其中,significant level=5%,已知的mean 即为Ho假设中的值且population 标准差已经提供 存在这样的mean distribution: 通过term ...
• Naiverelativism. While it’s certainly a more “critical” approach than ignorant certainty, naive relativism is still inadequate since it misses the whole point of critical thinking: arriving at a more complete,“less wrong”answer. • 天真的相对主义。尽管相对于无知的确定性而言,这无疑是...

According to the uncertainty principle, there is a relation between the uncertainties of energy \(\Delta E\) and any value \(\varphi \) $$\begin{aligned} \Delta E\Delta \varphi \sim \hbar \,\partial _t{\varphi }. \end{aligned}$$ (33) Since \(\partial _t\sim \Delta \varphi ...
