variables at DATA Step, while the MAX function at PROC SQL is quite straightforward. ***(7)MAX: find the maximum value for each column***; proc sql; select id, max(treat1) as effect1 'Effect after Treatment 1', max(treat2) as effect2'Effect after Treatment 2', max(treat3) as ...
a DATA step can contain multiple SET statements. 2. RETAIN的作用:对于数据集中新声明的变量,SAS会在data步循环执行开始时将其置为空值,而如果该变量是retain的变量,则不被置空。 The RETAIN statement prevents SAS from re-initializing the values of new variables at the top of the DATA step.Previous...

Example 2: Creating a table with Proc SQL versus creating it with a Data Step The simplest way of creating a SAS data set or table is to read into it all the variables and records of another SAS data set. In the code below, the Select * syntax retrieves all variables from the Measur...
This article demonstrates how to use PROC GENMOD to perform a Poisson regression in SAS. There are different examples in the SAS documentation and in conference papers, but I chose this example because it uses two categorical explanatory variables. Therefore, the Poisson regression can be visualized...
