A SET statement can contain multiple data sets; 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...

SAS Global Forum 2009 Foundations and Fundamentals Paper 136-2009 Understanding the SAS® DATA Step and the Program Data Vector Steven First, Systems Seminar Consultants, Madison, WI ABSTRACT The SAS system is made up of two major components: SAS PROCs and the SAS DATA Step. The DATA Step ...
In Chapter 2 we have seen that a SAS job consists of a series of statements divided into DATA steps and PROC steps. DATA steps are typically used to input and modify data. PROC steps are typically used to perform calculations and print results. This separation of tasks into two types of ...
Today, those limitations no longer apply, opening the door to more complex machine learning and deep learning algorithms that can handle large amounts of data in multiple passes. As a result, the standard descriptive, prescriptive and predictive capabilities of analytics have been augmented with ...
The data step will start with the data work using the Stats Rule on the work library. It is beneficial to manipulate the dataset in multiple steps with necessary actions. Data sets with interim steps for the work library to help the stored data sets with nervous manipulating the original file...
