将统计学和数据分析应用与研究结论是一项技术艺术,其中最常用的是p值(P-value),该值是从实验中计算出来的,它可用于判断实验中发现的结果是否具有统计学意义。 P值是一种用于评估统计发现的概率。它是研究者用来判断从实验中获得的结果是否只是偶然发生的概率,而不是实际存在的统计学显著性的概率。P值是一个在0-...

Hi. I am running a multiple regression analysis with [b,bint,r,rint,stats] = regress(y,X). Regarding 'stats' I have the following questions: 1) What is the critical value (alpha) for the F statistic? I mean which value does Matlab 'assume' (e.g. alpha=0.01...
