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. Previou...
Each time the SET statement is executed, SAS readsone observationinto the program data vector. SET reads all variables and all observations from the input data sets unless you tell SAS to do otherwise. A SET statement can contain multiple data sets; a DATA step can contain multiple SET statem...
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 ...
