A Guide to the RAT-STATS Statistical Software

 

Mastering RAT-STATS may be challenging without sufficient knowledge; gain confidence and understanding for effective usage.

RAT-STATS is a free software package developed and implemented by the Office of the Inspector General to help design, select, and extrapolate statistically valid random samples. The OIG primarily relies on the RAT-STATS software when performing audits of providers. Given the OIG's use of this software when performing audits of providers, it is important for providers, payers, and compliance professionals to have a good understanding of the RAT-STATS software. Unfortunately, the OIG has released a pair of lengthy documents that do little to explain the software in a digestible manner. This presentation will explain how to use and understand the RAT-STATS software in a user-friendly manner. The presentation explains the software's purpose, capabilities, and shortcomings. The presentation will also explain some key points to consider when scrutinizing and rebutting poorly performed opposing analysis.
