求问sas分组运行命令

有根据公司代码进行分组的面板数据，大概有3万组。
每一个公司，都需要进行一次回归分析。

如何使用一个程序，对三万组数据执行一个命令，并且把回归结果写在一起呢？

Unless I'm missing something, a simple by statement would do:

Proc reg data=xyz noprint outest=outest tableout;
By compantID;
Model y=x;
Run;

Proc reg data=xyz noprint outest=outest tableout;
By compantID;
Model y=x;
Run;

想请教您，如果我是做arima的分析呢？
可以用 proc arima data=aaa;
           by companyID;
吗？

I'm not familia with proc aroma, but I'd be surprised if by statement does not work. Why don't you try in SAS?
