感覺呀，我似乎缺乏很嚴重的溝通能力呀。
最近常常在Youtube上聽一些音樂合輯，卻感覺好多音樂合輯根本只是抄來抄去的吧

Statistic Test

以下為以日文統計專有名詞為主的筆記
參考書籍:大学四年間の図解統計学が10時間で学べる

基礎筆記

1. 分散$= \frac{\text{絕對偏差平方}}{\text{總數}}$

2. 標準偏差$=\sqrt{分散}$

3. 標準化$=\frac{\text{測定值-平均}}{\text{標準差}}$
   $\Rightarrow$通過標準化來使得分散一至為一

4. 共分散$=Cov(X,Y)=\frac{\Sigma(X-u_{x})(Y-u_{y})}{n}$

   $Cov(X,Y)=E(XY)-u_{x}u_{y}$

5. 母體相關係數$=r=\frac{\Sigma(X-u_{x})(Y-u_{y})}{n\sigma_{x}\sigma_{y}}=\frac{Cov(X,Y)}{\sigma_{x}\sigma_{y}}$
   樣本相關係數

6. 回歸直線

   設回歸直線為 $y=ax+b$

   $y=r\times \frac{\sigma_{y}}{\sigma_{x}} \times x +b$

   $\rightarrow 斜率a=r\times \frac{\sigma_{y}}{\sigma_{x}}=\frac{Cov(X,Y)}{\sigma_{x}^2}$

This is my first hexo.I spent about 5minutes to install and setup hexo. But github is too difficult for me to understand. So I don’t know even how can I open this text uptil my classmate rescue me~~

For these reason my hexo still can’t read on the Internet but just in the localhost which I have learned in the php experiement. Though it was so upsad that I havan’t push it on the Internet , it is still a amasing thing to setup a new blog by myself not the google blogger.

Welcome to Hexo! This is your very first post. Check documentation for more info. If you get any problems when using Hexo, you can find the answer in troubleshooting or you can ask me on GitHub.
