SAS 线性回归误差

Question

我是 SAS 的初级程序员，我在尝试做 LR 时遇到了一些问题。

我正在尝试对数据集（ads.csv，根据电视、广播和报纸数据预测销售额）运行多元线性回归

S_no,TV,Radio,Newspaper,Sales

1,230.1,37.8,69.2,22.1

2,44.5,39.3,45.1,10.4

3,17.2,45.9,69.3,9.3

4,151.5,41.3,58.5,18.5

但是，当我使用初始编码在 SAS 中运行线性回归来声明输出数据时，我收到一条错误消息：错误：必须提供输出 SAS 数据集。

options linesize=180 pagesize=180 nodate pageno=1;
libname Linreg1 "/folders/myfolders";
proc import datafile="/folders/myfolders/ads.csv";
out=Linreg1.output dbms=dlm replace;
delimiter=,;
getnames=yes;
run;

以下是这段小代码的完整日志：

1          OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;
 55         
 56         options linesize=180 pagesize=180 nodate pageno=1;
 57         libname Linreg1 "/folders/myfolders";
 NOTE: Libref LINREG1 was successfully assigned as follows: 
   Engine:        V9 
   Physical Name: /folders/myfolders
 58         proc import datafile="/folders/myfolders/ads.csv";
 ERROR: Output SAS data set must be provided.
 NOTE: The SAS System stopped processing this step because of errors.

任何帮助将不胜感激！

[编辑：正如 Reeza 在第一条评论中所说] 那里有额外的分号 - 你的 proc 导入行需要如下所示：

options linesize=180 pagesize=180 nodate pageno=1;
libname Linreg1 "/folders/myfolders";
proc import datafile="/folders/myfolders/ads.csv" out=Linreg1.output dbms=dlm replace;
delimiter=,;
getnames=yes;
run;
