RATS 7 的新特性如下:
  • New and Improved Wizards: RATS now offers more than two
    dozen menu- and dialog-driven "Wizards", providing point-and-click interfaces
    for everything from reading in data to estimating and analyzing VAR models.
    Many of the existing Wizards are now more powerful and easier to use.
  • Improved Graphics: Version 7 provides better looking
    graphs, and gives the user much more control over graph appearance.
  • New DSGE instruction: DSGE (for Dynamic Stochastic
    General Equilibrium models) analyzes linear and non-linear models with
    expectational terms, solving for a set of matrices which can be input into the
    DLM (state space model) instruction.
  • More IV/GMM Support: The four “least squares”
    instructions (LINREG and NLLS for single equations, SUR and NLSYSTEM for
    systems) now have a common set of options for handling GMM estimation in a
    more flexible way, including choice of method for updating the weight
    matrices. The biggest change here is the addition of GMM capabilities to SUR
    (Seemingly Unrelated Regressions).
  • New Functions: Version 7 adds thirty new built-in
    functions, bringing the total of new functions added since version 6.0 to
    almost ninety.
  • New Manuals: The revised RATS 7.0 manuals document all of
    the new features and changes introduced in Version 7, as well as those that
    appeared in incremental updates released since Version 6.0.
  • Simplified Syntax: Version 7 introduces a streamlined
    syntax for many instructions, with easy-to-remember options replacing longer
    lists of parameters. Note, however, that we still support the older
    syntax-RATS is largely backwards compatible to Version 4.
