The SAS DO Loop is one of the statements that enables to execution of the group of statements that access between the do and end statement. It repetitively iterated till the value of the variable index. It may be the condition like < less than or greater than > for other variables in th...

SAS迭代DO loop 0 to 9结合ARRAY产生一个数组下标超出范围错误。 下面的SAS例子,DO循环用于迭代数组元素来定位目标元素。...SAS中数组主要用于迭代处理如变量。SAS/IML更接近的模拟NumPy数组。但SAS/IML 在这些示例的范围之外。 ? 一个Series可以有一个索引标签列表。 ?...SAS示例使用一个DO循环做为索引下标插入...
data example_2; x = ‘Minnesota’; y = ‘Columbus’; run; The log presents the following message: /*日志输出如下信息*/ NOTE: The data set WORK.EXAMPLE_2 has 1 observation and 2 variables. 第二个例子展现了数据步的一个迭代过程如何生成5条观测。DO LOOP循环改变了执行的默认顺序。

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 ...
second and third arguments once rather than every time the COMPRESS function is called. Using the O modifier in the DATA step (excluding WHERE clauses), or in the SQL procedure, can make COMPRESS run much faster when you call it in a loop where the ...
