而“IF-THEN 数据集” 则是在 SAS 中用来进行数据的转化和筛选的技术。如果某个变量符合 IF 子句中设定的条件,那么就会执行 THEN 子句中的操作,否则不会进行操作。这个技术通常被用于创建新的数据集或对现有数据集进行加工。 这是一个简单的 IF-THEN 数据集语句的例子: ``` data new_dataset; set old_datas...

Task 1 :Suppose you are asked to exclude some of the observations in a SAS data set from an analysis that you are generating. For example, you want to exclude all IDs whose values are greater than 100. To accomplish this task, we can useIF, IF-THEN DELETE. Comparison Operators 1. IF...
IF-THEN/ELSE statements are simple and easy to use. However, IF-THEN/ELSE statements have their limitations. They are not always easy to read or to make changes to. They may also be less efficient than other methods that are available in SAS. Alternatives discussed include SELECT groups, AR...
