每个sample都有一个平均值,这些平均值的分布叫做sampling distribution of the sample mean. 由于population的分布是正态分布,这个分布也是正态分布,它服从N(μ, σ2/n),这里n为sample size. 根据中心极限定理,即使population分布不是正态的,sampling distribution也通常接近于正态分布。 例子 以下是应用机器学习项目...
As a statistics professor who teaches machine learning classes, this is among the top questions I get frequently asked by students. There are, of course, many ways to slice and dice it. In my opinion, if I had to boil it down to a few single points, I would highlight the following: ...

2. Material and Methods 2.1. Statistical Machine-Learning Workflow Sometimes, there is confusion regarding what machine learning involves. Here, we refer to statistical machine learning as inferring a model from data using an algorithm. We do not consider collecting, cleaning, and processing data as...
