How to Address PROC COMPARE Reporting Same Values as Different in SAS
How to Address PROC COMPARE Reporting Same Values as Different in SAS How to Address PROC COMPARE Reporting Same Values as Different in SAS Working with large datasets in SAS often requires comparing data between two tables. The PROC COMPARE procedure is an essential tool for this task, but sometimes it reports values as different even when they appear to be identical. This issue can arise from various causes, such as numeric precision differences, rounding issues, or formatting inconsistencies. In this post, we will explore common causes of this issue and how to resolve them. 1. Numeric Precision Issues SAS stores numeric values using floating-point precision, which can lead to small differences that aren't immediately visible. These differences may cause PROC COMPARE to report discrepancies even though the values seem the same. Solution: Use the CRITERION or FUZZ option to define an acceptable tolerance for differences. pro...
