Description
RATSTATS can be a difficult program to understand without proper knowledge.
RATSTATS is a free statistical software package developed by the U.S. government to help design, select, and extrapolate statistically valid random samples. Given the government’s reliance on RATSTATS, the software is routinely used by health care providers, payers, and compliance professionals when implementing their own statistical analysis. Unfortunately, RATSTATS can be difficult to use, and the 394page user guide and 245page companion manual are overwhelmingly technical. This topic will demystify RATSTATS in an easytounderstand manner and will help users to effectively employ the software. The material explains the software’s purpose, capabilities, and shortcomings along with a practical howto discussion for each of its modules. The information also addresses the common pitfalls of using RATSTATS. These topics are critical for those seeking to design and implement valid statistical sampling, as well as for those scrutinizing and rebutting poorly performed opposing analysis. This material will guide you and allow you to use RATSTATS with confidence.
