For validation of any dataset, PROC COMPARE is your first choice. Not only are datasets compared but also listings and summary reports. For summary reports fromPROC REPORTfor example, plan to save results in output datasets. Use the power of PROC COMPARE to not only compare variable attributes,...
• Primary programmer produces the dataset Step 1 • For TLF, dataset used in / output of proc report Step 2 • Reviewer re-produce the same output in parallel • Follow variable naming convention used by programmer • Generate the proc compare LST output and save it Step 3 • Us...
PROC COMPARE SAS Others 创建Library 压缩数据集,节省空间 导出log 导出html 导出Excel 导出图片到Excel SAS Code 获得data中的所有variables PROC CONTENTS DATA=dataset; ODS OUTPUT VARIABLES=output_dataset (KEEP=VARIABLE); RUN; 创建新table并依据多个variables进行left join PROC SQL; CREATE TABLE table1 AS ...
data combined_data; set dataset1; append from=dataset2; run; 4. 验证合并后的数据集 无论使用哪种方法合并数据集,都应该验证合并后的数据集是否满足需求。这可以通过检查记录数、字段值以及使用PROC PRINT、PROC COMPARE等SAS过程来实现。 sas proc print data=combined_data; run; * 使用PROC COMPARE比较...
看懂了validation那本书的第四章就没啥问题，一道是proc compare，然后最后两个dataset的obs数量不同，...
(1)格式:DATA [SASdataset[(dsoptions)]]…; (2)说明: SASdataset是这个DATA步正被创建的一个或几个SAS数据集的名字;dsoptions告诉SAS系统关于正被创建的SAS数据集的更多的信息。 (3)SAS数据集的名字的种类 ①省略数据集名 DATA; 等价于写: DATA _DATA_;每运行一次,SA...
proc contents data=hsb2; run; SAS导入数据:SAS recognizes the file type to be imported by file extension. 对数据长度的限制 在一些操作环境,SAS假定外部文件的纪录对最长为256(一行数据包括空格等所有字符在内的长度),如果预计读入的纪录长度超过256,可在Infile语句中使用LRECL=n 这个命令。
output(dataset: 'uni'); stop; run; 如果重复记录是需要保留以备后用则可以用下面几种方法: DATA步,程序如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 proc sort data=sashelp.class out=class; by WEIGHT; run; data uni dup; set class; by WEIGHT; if first.WEIGHT and last.WEIGHT ...
The most common method in SAS to obtain validation/QC pass for a dataset is to obtain a match via Proc Compare. Typical desired output would be... 3 4 However this ideal doesn’t always materialize. In the event of which debugging is required to find out whether the problem is in the...
testing with PROC COMPARE and revisingthe code as we did writing it in the first place. Step 6: Documentation Once the validation process was complete we created an archive that holds: (1) the PROC COMPARE output showing the matching results, (2) the test input dataset, (3) the Diet...
