Question

我是SAS的初级程序员，我遇到了一些试图做LR的问题。

我正在尝试对数据集运行多元线性回归（ads.csv，预测基于电视，广播和报纸数字的销售额）

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

然而，当我使用初始编码声明输出数据在SAS中运行线性回归时，我得到一个错误：ERROR：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;

以下是这小段代码的完整日志：

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.

非常感谢任何帮助！

[编辑：正如Reeza在第一条评论中所述]那里还有多余的分号-您的proc导入行需要阅读如下：

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;
