致精进的你:
同学,f(q)是对应的概率密度函数,如你上传的图片所示,中间f(q)大,两端f(q)小哈
The real talent is resolute aspirations.
真正的才智是刚毅的志向。

This will increase the probability mass f(q) and reduce p, the probability in the left tail. 教材这么写,为什么我觉得当f(q)变大,向中间走,p变大呢?

同学,当bin size h增大,q is in the range也会增大,the left tail probability, p, is the area to the left of range for a standard normal distribution因为带了负号,所以从数值上看是变小的哈。将notes作为教材学习是不推荐的哈,因为notes整体上逻辑不严谨且知识点重点不突出,建议以我们的课程讲义为主。
