New Project


opens a dialog that lets you create a new project, assign it a name and description, and make it the active project.

Open Project


opens a dialog that lets you select and load a previously saved project.

Save Project


saves the current state of the system (including all the models fit to a series) to the current project catalog entry.

Save Project as


saves the current state of the system with a prompt for the name of the catalog entry in which to store the information.

Clear Project


clears the system, deleting all the models for all series.

Save Forecast


writes forecasts from the currently highlighted model to an output data set.

Save Forecast As


prompts for an output data set name and saves the forecasts from the currently highlighted model.

Output Forecast Data Set


opens a dialog for specifying the default data set used when you select "Save Forecast."

Import Data


is available if you license SAS/Access software. It opens an Import Wizard, which you can use to import your data from an external spreadsheet or data base to a SAS data set for use in the Time Series Forecasting System.

Export Data


is available if you license SAS/Access software. It opens an Export Wizard, which you can use to export a SAS data set, such as a forecast data set created with the Time Series Forecasting System, to an external spreadsheet or data base.

Print Setup


opens the Print Setup window, which enables you to access your operating system print setup.

Close


closes the Develop Models window and returns to the main window.

Edit


Fit Model


Automatic Fit


invokes the automatic model selection process.

Select From List


opens the Models to Fit window.

Smoothing Model


opens the Smoothing Model Specification window.

ARIMA Model


opens the ARIMA Model Specification window.

Custom Model


opens the Custom Model Specification window.

Combine Forecasts


opens the Forecast Combination Model Specification window.

External Forecasts


opens the External Forecast Model Specification window.

Edit Model


enables you to modify the specification of the currently highlighted model in the table and fit the modified model. The new model replaces the current model in the table.

Delete Model


deletes the currently highlighted model from the model table.

Refit Models


All Models


refits all models in the table by using data within the current fit range.

Selected Model


refits the currently highlighted model by using data within the current fit range.

Reevaluate Models


All Models


recomputes statistics of fit for all models in the table by using data within the current evaluation range.

Selected Model


recomputes statistics of fit for the currently highlighted model by using data within the current evaluation range.

View


Project


opens the Manage Forecasting Project window.

Data Set


opens a Viewtable window to display the current input data set.

Series


opens the Time Series Viewer window to display plots of the current series. This is the same as the View Series Graphically icon.

Model Predictions


opens the Model Viewer to display a predicted versus actual plot for the currently highlighted model. This is the same as the View Selected Model Graphically icon.

Prediction Errors


opens the Model Viewer to display the prediction errors for the currently highlighted model.

Prediction Error Autocorrelations


opens the Model Viewer to display the prediction error autocorrelations, partial autocorrelations, and inverse autocorrelations for the currently highlighted model.

Prediction Error Tests


opens the Model Viewer to display graphs of white noise and stationarity tests on the prediction errors of the currently highlighted model.

Parameter Estimates


opens the Model Viewer to display the parameter estimates table for the currently highlighted model.

Statistics of Fit


opens the Model Viewer window to display goodness-of-fit statistics for the currently highlighted model.

Forecast Graph


opens the Model Viewer to graph the forecasts for the currently highlighted model.

Forecast Table


opens the Model Viewer to display forecasts for the currently highlighted model in a table.

Tools


Diagnose Series


opens the Series Diagnostics window to determine the kinds of forecasting models appropriate for the current series.

Define Interventions


opens the Interventions for Series window to enable you to edit or add intervention effects for use in modeling the current series.

Sort Models


sorts the models in the table by the values of the currently displayed fit statistic.

Compare Models


opens the Model Fit Comparison window to display fit statistics for selected pairs of forecasting models. This is unavailable if there are fewer than two models in the table.

Generate Data


opens the Time Series Simulation window. This window enables you to simulate ARIMA time series processes and is useful for educational exercises or testing the system.

Options


Time Ranges


opens the Time Ranges Specification window to enable you to change the fit and evaluation time ranges and the forecast horizon. This action is the same as the Set Ranges button.

Default Time Ranges


opens the Default Time Ranges window to enable you to control how the system sets the time ranges for series when you do not explicitly set time ranges with the Time Ranges Specification window. Settings made by using this window do not affect series you are already working with; they take effect when you select a new series.

Model Selection List


opens the Model Selection List editor window. Use this action to edit the set of forecasting models considered by the automatic model selection process and displayed by the Models to Fit window.

Model Selection Criterion


opens the Model Selection Criterion window, which presents a list of goodness-of-fit statistics and enables you to select the fit statistic that is displayed in the table and used by the automatic model selection process to determine the best fitting model. This action is the same as clicking the button above the table which displays the name of the current model selection criterion.

Statistics of Fit


opens the Statistics of Fit Selection window, which presents a list of statistics that the system can display. Use this action to customize the list of statistics shown in the Model Viewer, Automatic Model Fitting Results, and Model Fit Comparison windows and available for selection in the Model Selection Criterion menu.

Forecast Options


opens the Forecast Options window, which enables you to control the widths of forecast confidence limits and control the kind of predicted values computed for models that include series transformations.

Alignment of Dates


Beginning


aligns dates that the system generates to identify forecast observations in output data sets to the beginning of the time intervals.

Middle


aligns dates that the system generates to identify forecast observations in output data sets to the midpoints of the time intervals.

End


aligns dates that the system generates to identify forecast observations in output data sets to the end of the time intervals.

Automatic Fit


opens the Automatic Model Selection Options window, which enables you to control the number of models retained by the automatic model selection process and whether the models considered for automatic selection are subset according to the series diagnostics.

Include Interventions


controls whether intervention effects defined for the current series are automatically added as predictors to the models considered by the automatic selection process and displayed by the Models to Fit window. When the Include Interventions option is selected, the series interventions are also automatically added to the predictors list when you specify a model in the ARIMA and Custom Models Specification windows. A check mark or filled check box next to this item indicates that the option is turned on.

Print Audit Trail


prints to the SAS log information about the models fit by the system. A check mark or filled check box next to this item indicates that the audit option is turned on.

Show Source Statements


Controls whether SAS statements submitted by the forecasting system are printed in the SAS log. When the Show Source Statements option is selected, the system sets the SAS system option SOURCE before submitting SAS statements; otherwise, the system uses the NOSOURCE option. Note that only some of the functions performed by the forecasting system are accomplished by submitting SAS statements. A check mark or filled check box next to this item indicates that the option is turned on.
