•
Bartlett small-sample correction of the tests for the cointegrating
rank and hypotheses on Beta.
•
A new ¡°CATSmining¡± automated model-selection procedure.
•
Estimation and hypothesis testing of the I(2) model, including testing
hypotheses on the multi-cointegrating relations and the I(1) relations
among the system variables
•
Estimation of structural moving average models.
•
System reduction tests for lag length determination.
•
Missing observations in data allowed.
•
Updated recursive estimation routine includes new tests for eigenvalue
fluctuation, constancy of the cointegrating space and the log-likelihood
function.
•
Allows for ¡°backwards¡± recursion for investigating parameter constancy
over the beginning of the sample.
•
For most model specifications, CATS now reports the correct critical
values and p-values for the rank test. For other models, you can
simulate the critical values using a built-in procedure.
•
Includes a procedure for estimation and identification of structural
moving average models.

•
All-new user interface, with separate menus for various categories
of operations, including I(1) analysis, I(2) analysis, graphics,
and automated tests.
•
All model settings, including the deterministic terms and lag structure,
are menu-controlled, so you can now change the underlying VAR model
without quitting and re-starting CATS.
•
All procedure settings, such as maximum number of iterations and
convergence criteria for the switching algorithms, screen output
format, and more, can be set via a "Preferences" dialog
box.
•
The estimated model can now be exported as a RATS ¡°MODEL¡± making
it much easier to compute forecasts and impulse responses.
•
The graphs created by CATS can be customized.
•
Output can be exported in tex or csv formats.
•
Restrictions can be saved and re-loaded, making it easier to replicate
analyses or continue your work at a later time.
•
CATS offers the option of running in a true batch mode that does
not require user interaction to generate basic output. This allows
it to be used in loop.

•
¡°Batch¡± tests for long-run exclusion, weak exogeneity, and stationarity
on all model variables (now available from the cats menu). Also
includes a test for unit vectors in alpha, which corresponds to
testing if the cumulated disturbances of any of the variables do
not enter the common trends.
•
Support for partial systems, models with structural breaks, and
various forms of dummy variables.
•
Multivariate and univariate tests of the estimated residuals.
•
Recursive estimation for assessing constancy of the estimated model
parameters, including tests for constancy of the estimated eigenvalues,
the cointegrating space, the log-likelihood function, the parameters
of an identified system, and the adequacy of one-step-ahead predictions.
•
Options for testing hypothesis on the long-run relations in Beta
as well as on the adjustment coefficients in Alpha.
•
Choice of normalization for each cointegrating vector (CATS 2 simplifies
this by suggesting default choices).
•
Estimation of the parameters of the moving average model, e.g. the
long-run impact matrix C and the loadings to the common trends (with
asymptotic t-values).
•
A large variety of preset graphics illustrating various key aspects
of the estimated model
