使用do循环在SAS中创建新变量
我有一个SAS计划，有一个基准年的数据和五个预测年。所有预测年都有相同的计算，但只使用上一年的数据作为计算的基准年。我希望避免复制数据5次，而只是更改变量名的后缀。如果只有一个预测年，并且有一个do循环或一个数组来更改变量名的后缀，那就太好了。以下是我根据您的输入更新的代码：使用do循环在SAS中创建新变量,sas,sas-macro,do-loops,Sas,Sas Macro,Do Loops,我有一个SAS计划，有一个基准年的数据和五个预测年。所有预测年都有相同的计算，但只使用上一年的数据作为计算的基准年。我希望避免复制数据5次，而只是更改变量名的后缀。如果只有一个预测年，并且有一个do循环或一个数组来更改变量名的后缀，那就太好了。以下是我根据您的输入更新的代码： *Start macro loop - takes two parameters, the first year of the dataset to be created and the last year; %macro

非常感谢你的帮助！我几乎可以让它工作了，但我一直在思考如何称呼maco。我在哪里放置：%loop（年份开始=15，年份结束=20）；我已经在%宏循环区域和代码末尾尝试过了。在宏循环之后，我仍然没有得到任何输出。我不知道我是否做错了什么。下面是我的代码的结尾：Run；%结束*do循环结束；%修补*宏结束；%循环（开始年份=18，结束年份=20）；您正在从%macro循环（）运行代码。。；起点？我根据您的输入更新了代码。我对宏非常陌生。我真的很感谢你的帮助。我的%loop语句无效或使用顺序不正确仍然会给我带来错误非常感谢您的帮助！我几乎可以让它工作了，但我一直在思考如何称呼maco。我在哪里放置：%loop（年份开始=15，年份结束=20）；我已经在%宏循环区域和代码末尾尝试过了。在宏循环之后，我仍然没有得到任何输出。我不知道我是否做错了什么。下面是我的代码的结尾：Run；%结束*do循环结束；%修补*宏结束；%循环（开始年份=18，结束年份=20）；您正在从%macro循环（）运行代码。。；起点？我根据您的输入更新了代码。我对宏非常陌生。我真的很感谢你的帮助。我的%loop语句无效或使用顺序不正确，这仍然会给我带来错误
