Enhancements in SAS/ETS® 14.1 Software

Overview

SAS/ETS 14.1 introduces the X13 procedure and enhancements to many other procedures.

X13 Procedure

Because the US Census Bureau has included the X-12-ARIMA methodology in the X-13ARIMA-SEATS program, the X12 procedure has been renamed the X13 procedure. You can continue to specify PROC X12 as before, but the X-12-ARIMA methodology will be based on the current method in the X-13ARIMA-SEATS method, including enhancements and improvements.

The following features have been added to the X13 procedure:

COUNTREG Procedure

The following features have been added to the COUNTREG procedure:

HPCOUNTREG Procedure

The following features have been added to the HPCOUNTREG procedure:

HPPANEL Procedure

The following features have been added to the HPPANEL procedure:

MODEL Procedure

The %EQAR and %EQMA macros have been added to the MODEL procedure. Model programs that are expressed using general form equations can now use the %EQAR macro to specify autoregressive error processes or the %EQMA macro to specify moving average error processes. The %EQAR and %EQMA macros modify general form equations similar to how the %AR and %MA macros modify normal form equations.

PANEL Procedure

The following features have been added to the PANEL procedure:

QLIM Procedure

The following features have been added to the QLIM procedure:

SASECRSP Interface Engine

If you install SAS/ETS on a Windows system, you no longer need to install the CRSPAccess API, because it is now distributed automatically during the installation. Before you run SASECRSP, your Windows setup requires that the CRSPDB_SASCAL environment variable be set to the path where your database calendar files reside.

SASEFRED Interface Engine

The following features have been added to the SASEFRED interface engine:

SASEXCCM Interface Engine

If you install SAS/ETS on a Windows system, you no longer need to install the CRSPAccess API, because it is now distributed automatically during the installation. Your Windows setup does not require any special environment variables.

SASEXFSD Interface Engine

The following features have been added to the SASEXFSD interface engine:

SASEQUAN Interface Engine

The following features have been added to the SASEQUAN interface engine:

SSM Procedure

The DEPLAG statement has been added to the SSM procedure. It simplifies the specification of models that have lagged values of response variables in the observation equation. The DEPLAG statement enables you to define a linear combination of lagged response variables, which can be subsequently used as a right-hand-side term in the MODEL statement. Models that include lagged response variables are permitted only if the data form a time series (either univariate or multivariate).

VARMAX Procedure

The following features have been added to the VARMAX procedure:
