Version 7.3 will begin shipping around the beginning of February, 2010. We'll be updating these pages with details shortly, but in the meantime, see our January 2010 RATSletter for an overview of Version 7.3.
For more detailed information, download a copy of the RATS 7.3 Supplement that ships with the new version. This document lists all of the new features in 7.3, as well as those features added in 7.1 and 7.2
Below is a list of the major improvements in Version 7.2. See the March, 2009 RATSletter for more details. RATS 7.0-7.2 provides information on all the improvements introduced in 7.0, 7.1, and 7.2
Thanks to compiler improvements, we've nearly doubled the speed at which the Windows version does most computations. You'll find that many complex estimation and simulation tasks will now take roughly half as long as before.
The Professional version of WinRATS now ships with a 64-bit version of the program, allowing you to handle much larger data sets on systems running 64-bit XP or Vista. The 32-bit version is also still included.
Almost all features of the Census X12-ARIMA seasonal adjustment methodology have now been incorporated into the Pro version of RATS, through improvements to the X11 and BOXJENK instructions. This includes log-additive and pseudo-additive adjustments, improved handling of outliers and calendar effects, and more.
Users with the Professional version 7.2 can now access the St. Louis Federal Reserve Bank's FRED database directly from within RATS (requires active internet connection).
New options for RegARIMA modelling, where the emphasis is on the regression model rather than the time series model for errors. BOXJENK has been optimized to run faster, particularly with seasonal components.
This instruction (for Dynamic Stochastic General Equilibrium models) has improved computational and error-checking capabilities, and a new option for exogenous shocks models.
New menu-driven wizards for running unit root tests, density estimation, and non-parameteric regressions.
Users with a current Update Subscription will receive their copies of Version 7.2 on CD automatically.
For other users, the basic price to update to Version 7.2 is $25 for users with Version 7.0 or 7.1, and $150 for users with older versions of RATS (6.35 or older). See RATS Updates for details. If you have a multi-user license, please contact us for a quote on updating to 7.2.
