SAS Day 27: Proc Means We useStatistical summaryto demonstrate the mean, median, max, min, Q1, Q3… In SAS we can either use Proc Means or Proc Univariate to achieve the goals. Today we will introduce how to generate statistical summary usingProc Means. Basic Syntax: proc means data= du...
如果用SAS,那么大猫首先需要用Proc Means来统计全国的均值,然后通过Output语句将结果输出,假设输出数据集是Means吧,然后大猫还得把数据集Means给Join回原来的数据集,关键是在Join的过程中还要用到 If _N_ Eq 1 Then Set...这种非常Tricky的技巧,这对于初学者和不懂SAS的PDV(Program Data Vector)机制的人简直是...
Do I need to change the syntax of proc means to take advantage of the Hadoop platform? I thought the SAS Workspace server would automatically connect to the HadoopNode and proc means would be performed in parallel by multiple computers. Am I wrong? An additional question: ...

过程步（procstep）的概念 过程步是指用以调用某个SAS过程（SASprocedure）的一组SAS语句所构成的相对独立的程序单元。过程步均以SAS系统中包含的各类过程（procedure）为基础，其中所能包含的语句和语句中的选项均表现为相对固定的形式，取决于所调用的具体过程。用户所能调用的SAS过程取决于安装...
Syntax The basic syntax for calculating arithmetic mean in SAS is − PROC MEANS DATA = DATASET; CLASS Variables ; VAR Variables; Following is the description of parameters used − DATASET− is the name of the dataset used. Variables− are the name of the variable from the dataset. ...
