Tutorial: Identifying and Handling Missing Values in SAS with the MISSING Function

In the world of data science, especially within the SAS environment, robust data management forms the core foundation of reliable statistical analysis and precise reporting. A ubiquitous challenge faced by data analysts is the presence of missing values—data points that are undefined, unrecorded, or simply absent. If these gaps are not properly identified and addressed, […]
