When comparing datasets, there are three main levels that can impact differences. It is also helpful to know if the two datasets are expected to be the same or not to validate the dataset. For example an updated dataset is expected to have more records than an older dataset but may not h...

对于临床试验方向的sas programmer来说,由于QC这个工作流程的存在,proc compare 过程步是sas programmer 应用相当多的工具。生成的SDTM、ADaM、TFL和其他中间数据集均需要使用到proc compare。本文旨在帮助读者可以高效、正确的使用这个过程步。即使目前对于多数公司而言,compare 过程很可能是在一个很大的macro工具中,但了解...

While PROC COMPARE is a useful tool, it can also beintimidating. There are dozens of options to be aware of and the output has several sections. If you were interested in doing asimple comparison, wouldn't it be great if there was a simple tool to do it? Well there is! This paper ...

There are 2 datasets named "one" and "two" with 696 and 695 observations respectively and same variable "id". How to write out this one observation which is not present in "two" dataset? For example with the following syntax id=x. Many thanks in advance. 0 Likes Reply 1 ACCEPTED SOL...
Example: Data Set: ID NAME B1 B2 C1 B3 B1 – B3would returnB1 B2 B3 B1– B3would returnB1 B2 C1 B3 50. What is the basic syntax style in SAS? Important points for running a SAS program are: A DATA statement, which names our data set ...
数据清理阶段需建立双重核查机制。原始数据录入后,采用SAS的PROCCOMPARE程序比对不同版本数据库差异,设置缺失值处理规则。离群值判断采用国际协调会议(ICH)E9指南推荐的箱线图法结合临床医学判断,使用PROCUNIVARIATE进行数据分布检验,避免主观剔除有效数据。随机化分析需遵循意向治疗原则。在SAS环境中构建RANUNI函数生成...
proc print data=examp2; Sample Ouptut: The above example first we need to create and set the datasets. Then using the datalines we can assign the inputs with two columns. We need to set the dataset example on the lag function.
