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...
PROC COMPARE: Misleading Output Solution : %threeN Programmatically validates PROC COMPARE output Generates a html output file with ‘Pass / Fail’ status flag for each output file along with important base and compared datasets attributes The status is flagged as Pass whenever the output file meets...
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...
