What’s New in SAS High-Performance Forecasting 4.1
Overview
SAS High-Performance
Forecasting 4.1 coincides with SAS 9.3. Each release provides new
features while maintaining all the capabilities of previous releases.
New features in SAS
High-Peformance Forecasting 4.1 are briefly summarized here:
-
The HPF procedure supports new
ODS plots.
-
The HPFDIAGNOSE procedure includes
support for combined models and auxiliary data set support.
-
The HPFENGINE procedure includes
support for combined models, a generalized model selection topology,
auxiliary data sets, new ODS plots, and more.
-
The HPFSELECT procedure includes
support for defining model combination lists.
-
HPFTEMPRECON is a new procedure
to perform temporal reconciliation of time series forecasts that are
generated at two different frequencies. Temporal reconciliation is
commonly referred to as benchmarking.
HPF Procedure Enhancements
The HPF procedure contains
the following new features:
-
New ODS plots and plot options
are available. You can plot the periodogram for the error series or
a combined pediodogram and spectral density estimate plot. You can
also generate the prediction error correlation plot matrix.
HPFDIAGNOSE Procedure Enhancements
The HPFDIAGNOSE procedure
contains the following new features:
-
Auxiliary data set support enables
the HPFDIAGNOSE procedure to use other data sets as additional input
sources for explanatory variables that are needed during the run of
the procedure. Previously all variables that were required during
the procedure run had to be physically present in the primary DATA=
data set.
-
The COMBINE statement directs the
HPFDIAGNOSE procedure to generate a model combination list for the
set of automatic models that are generated from its time series diagnostics.
This model combination list is included in the generated model selection
list as another candidate forecast for the HPFENGINE procedure to
consider in its forecast selection process.
HPFENGINE Procedure Enhancements
The HPFENGINE procedure
contains the following new features:
-
New ODS plots and plot options
are available. You can plot the periodogram for the error series or
a combined pediodogram and spectral density estimate plot. You can
also generate the prediction error correlation plot matrix.
-
Auxiliary data set support enables
the HPFENGINE procedure to use other data sets as additional input
sources for explanatory variables that are needed during the run of
the procedure. Previously all variables that were required during
the procedure run had to be physically present in the primary DATA=
data set.
-
The FORCEBACK option enables you
to change the default behavior so that a BACK= region is strictly
enforced across all BY groups.
-
The OUTACCDATA= option directs
the HPFENGINE procedure to capture variable information from the run
to feed into the HPFTEMPRECON procedure.
-
The HPFENGINE procedure supports
a more general model selection topology. Termed the forecast model
selection graph, it remains semantically compatible with the previous
model selection list.
-
The HPFENGINE procedure supports
combined models as part of its automated model selection process.
User-defined combined model lists are created through the HPFSELECT
procedure. The HPFDIAGNOSE procedure can optionally create combined
model lists as part of its custom model generation process.
HPFSELECT Procedure Enhancements
The HPFSELECT procedure
contains the following new features:
-
The COMBINE statement directs the
HPFSELECT procedure to create a combined model list. Statement options
enable you to control different aspects of the forecast combination
process for the candidate models identified in the SPEC statements.
HPFTEMPRECON Procedure
The HFTEMPRECON procedure
is a new procedure.
