我对在SAS上执行宏非常陌生,所以如果我的问题看起来很基本,请提前道歉。 如果在临时工作文件中发现的观测值最少,我希望执行宏的一部分。 如果观察次数最少,则宏应执行该临时工作文件的proc导出,否则它只会在日志上生成错误消息。 我不确定我做错了什么,临时工作文件有超过1个观察值,我希望宏运行,但它会生成错误...
首先创建一个 Annotate Data Set, 这个DataSet中包含了:一些 Function 和 Function执行时需要的参数, 这个DataSet的每一条观测 指定了对plot 的一个操作(例如添加一段文本文字); 其中 Dataset 的 变量“Function” 指定 要执行的Function名称,例如Function的值时“text”,表示添加一段文本,而在已经初步绘制的graph中...
(The number of observations) 把NOBS赋值给var。NOBS=总在PDV之前执行, http://blog.sina.com.cn/s/blog_5e55ce3d0101peid.html ⑤ drop/keep/lable/length/format等是对数据变量的描述性(声明)语句或变量,对PDV循环的初始化没有影响。 Set命令相当于完成了在pdv定义变量(变量名为列名),同时赋值给变量(obs...
SAS数据清理与分析技术指南说明书
Observation number 输出观测编号,也就是行号,或者说行索引;方法肯定很多,比如SAS是用_n_变量,R则可以row.names() # R code row.names(iris) # SAS code data _null_; set sashelp.class; put _n_; run; Keep unique values 这种可以分成两种情况: ...
Data set stats is shown below. The n and mean values are listed under variables named after the corresponding analysis variable. The type of statistic in each observation is indicated by the _STAT_ variable.Obs _TYPE_ _FREQ_ _STAT_ x y 1 0 1 N 1 1 2 0 1...
There are plenty of methods that could be applied to the missing data, depending on the goal of the clinical trial. The most common and recommended is multiple imputation (MI), and other methods such as last observation carried forward (LOCF), observed case (OC) and mixed model for repeated...

The actual format of your dataset should probably be changed as this will only present problems for you in future analysis. You should try limiting the number of blank fields as much as possible as eliminating repeats is something proc report does pretty well. I would also suggest name gets ...
