SAS宏是一种宏语言,用于在SAS程序中定义和调用可重复使用的代码块。 SAS宏Do循环的基本语法如下: 代码语言:txt 复制 %macro macro_name; %do index=start_value %to end_value %by increment; /* 代码块 */ %end; %mend macro_name; 其中,macro_name是宏的名称,index是循环变量的名称,start_value是循环...
这是我的sas程序: %let path=\\xxxx.yy.pt\aaa$\INFO\; %let initial_year=2019; %let initial_month=2; %let final_year=2021; %let final_month=1; %Macro import_loop; %if &final_month >= &initial_month %then %do; %DO x = &initial_year %TO &final_year; %DO i = &initial_mon...
Not entirely sure where you are going with: "input various value of r, n, a and b.", but in either way as @PaigeMiller has stated, datastep loop and in fact all programming is better done in Base SAS, and only use Macro where it really adds value for the amount of effort it is...
The power of recursive SAS® macros - How can a simple macro do so much ?A recursive macro is a perfect solution if you need to apply a `fixed process' in a nested application. Using regular macros, you would need to know all the dimensions or levels of nesting in order to set up...
By Rick Wicklin on The DO Loop February 17, 2025 Topics | Analytics Learn SAS Programming Tips Many people have an intuitive feel for residuals in least square models and know that the sum of squared residuals is a goodness-of-fit measure. Generalized linear regression models use a different ...

大佬们,我刚学sas,想请教一个简单的问题,括号里这个%macroimport;%do i =1%to13;proc import datafile="导入路径\day_stock &i."(为什么&i后面不能加dbf,否则会重复)out=stock&idbms=dbf replace;quit;%end;%mend;%import; 巡山的大王@ 高级粉丝 3 你这里指的dbf应该是文件格式,试试再加一个点看看能...
Simulation of Categorical Data by Using the SAS/IML Language The program statements are similar, but in the SAS/IML language you use the RANDSEED function to set the random number seed and the RANDGEN function to fill an entire matrix of values in a single call: ...
本篇论文是希望藉助SAS MACRO程序,提出一个能解决建立多项式模型上的困恼。多项式模型在统计分析上一直是被忽略的,这可以很清楚的知道因为在所有的统计分析的出版品中很难找到以多项式回归为主提的例子。这原因无非是无法解决大量变量的模型建立与分析。举例来说要建立一
