SAS data set is a SAS file, which holds data. Data should be in the form of a SAS data set to get processed. A SAS data set contains data value organized as a table of observations and variables to process by SAS. Rows are defined as Observations and Columns are defines as Variables...
就是字面意思：输入的数据中没有观测值，数据为空。
具体用途:If the REUSE= option is set to YES, observations that are added to the SAS data set are inserted wherever enough free space exists, instead of at the end of the SAS data set,当确定用reuse后,sas不会再数据集尾上添加数据,而会在有足够空白的地方添加数据 ...

TITLE "SAS test data set"; RUN; 打印结果 示例数据打印结果 读取非标准格式的原始数据(格式化输入) SAS中的标准格式只有两种类型,字符型和数值型。但是日常使用过程中还需遇到像日期和内嵌逗号的数值等数据。这个时候简单的列表读取会导致数据格式有误。在SAS中通过使用输入格式告知计算机如何解读这些数据。
在SAS中处理多个数据集的情况太多,这里不可能一一列出,因此,本文仅讲一点内容,抛砖引玉: 这里讲的例子是两个数据集合并,以及关键词IN(Creates a variable that indicates whether the data set contributed data to the current observation)。 首先创建两个...
