SAS/STAT Topics Area

There’s a lot of stuff in SAS/STAT software. Like 10,000 pages of documentation worth. It can be overwhelming to determine what areas are covered and what procedures you should use. We introduced a Topics tab in the online documentation a few releases ago, and there are corresponding pages in our focus area that briefly describe the topic areas and the procedures that perform analyses for those areas. In the future, we’ll provide more linkage between the documentation and other web resources (videos come to mind), but for now, just use the URL and see if this helps to navigate the SAS/STAT landscape.
