SAS数据集操作:基础概念与实践说明书
Simple Histogram A simple histogram is created by specifying the name of the variable and the range to be considered to group the values. Example In the below example, we consider the minimum and maximum values of the variable horsepower and take a range of 50. So the values form a group...

run; 说明:method用来指定随机抽样方法的,其中SRS是指不放回简单随机抽样(Simple Random Samping);urs是指放回简单随机抽样(Unrestricted Random Sampling);sys是指系统抽样(Systematic Sampling)。seed用来指定随机种子数,为非负整数,取0则每次抽取的样本不同,若取大于0的整数,则下次抽样时若输入相同值即可得到相同的...
SAS执行过程中,在DATA步迭代之初都会把PDV(Program Data Vector)中非保留和非输入变量设为缺失值。SAS从输入文件或一个SAS数据集读入数据到PDV(Program Data Vector)中,同时会替掉以前存在的值。 DATA步处理过程:系统介绍 Example 4 – simple default – no reading of input data /*简单默认-没有读入input数据...
PROGRAM EDITOR窗口:主要用于打开SAS程序文件(SAS程序文件扩展名为 *.sas)、编辑和修改SAS程序、并提交全部或部分SAS程序。根据程序中编码的性质可以显示不同的颜色,并且对SAS语言进行语法检查。在SAS中可同时打开多个Editor窗口进行操作。Log窗口:浏览程序运行信息、错误提示。黑色表示的程序行,兰色表示提示信息,绿色...
