General Information on RATS

RATS (Regression Analysis of Time Series) is a fast, efficient, and comprehensive time series analysis and econometrics software package. RATS makes simple tasks easy to accomplish, while its command-driven interface and extensive programmability also make it a very flexible and powerful tool for more complex jobs.

The Windows and Macintosh versions feature an interactive editor that allows you to create, test, and run RATS programs; view, save, and print text and graphs; access on-line help; and much more. While running in interactive mode, you can quickly experiment with different models or procedures, without having to repeat earlier steps each time.

All versions of RATS also offer batch mode operation. In batch mode, RATS automatically reads and executes instructions from one or more input files, and saves the output to disk.
