一、參考代碼

二、安裝scipy

如果代碼運行過程報錯，顯示?

import scipy.stats 有錯誤，但是又安裝了scipy ， 則可能是scipy的版本太低，換成1.6版本。（低版本的文件大小明顯小的很多，才十幾M，而1.6版本則32M多，所以可能是很多子文件未包括在內）

安裝方法同下。

三、第三方庫安裝? statsmodels

第一種方式：電腦中dos命令行模式下? 直接 pip install statsmodels即可成功完成， 如果安裝一半報錯結束，則進入第二種方法。

?

第二種方式：

pypi官網是很多第三方庫文件的匯總網站，很多庫可以在上面找到。 注意自己的Python版本，電腦操作系統版本等再下載。

網址：https://pypi.org/project/statsmodels/#files

?

?

下載完文件，放入自己電腦的Python安裝目錄下的?目錄中E:\Python\Python38\Lib\site-packages 參考自己電腦的安裝目錄。

?

cmd進入dos界面，進入到E:\Python\Python38\Lib\site-packages目錄執行命令pip install statsmodels-0.12.2-cp38-cp38-none-win_amd64.whl安裝成功后退出
