Output from a modelling procedure

The results of the modelling procedure performed with the TRAMO or the RegARIMA models are stored in the Documents section, which belongs to the Modelling node of the Workspace. These documents are displayed in the TramoDoc (for TRAMO) and the RegArimaDoc windows (for RegARIMA).

There are several ways to create the document. One of them is to choose from the main menu an option Statistical methods → Modelling → Single Analysis → Tramo/RegArima. By using this option a default specification will be assigned to this document (TRfull when Tramo is chosen, RG4 when RegArima is chosen). It means that the default specification will be used for modelling of the series inserted into document’s window.

Activating a document for a single time series

Alternatively, the document can be created directly in the Workspace window, using the local menu options available for the selected specification. Expand the list of specifications under the Modelling $\rightarrow \ $specifications $\rightarrow \ $tramo/regarima node. Then, right click on the specification name to open the local menu and then chose an option Create document.

Creating a new document from the Modelling specifications level

An empty document will be added to the relevant place in the Modelling $\rightarrow \ $documents section of the Workspace window and the specification chosen by the user will be assigned to it.

An empty document can be also created on the Modelling → documents level. It can be done by marking a modelling method in the navigation tree (tramo or regarima) and choosing an option New from the local menu.

Creating a new document in the Documents section

All documents are added to the Modelling → documents part of the Workspace window. Once the workspace is saved all the documents defined for this workspace are saved as well. The user may then investigate the saved results of the modelling and update them using the Refresh data option from the TramoSeats Doc menu or the RegArima Doc menu, depending on the node, to which the specific document belongs to (tramo or regarima).

Location of the documents for modelling with the RegARIMA model

To use the templates created directly in the Workspace window, double click on its name to display it. To perform an analysis, drag and drop the series from the Workspace window to the document window.

Choosing a time series for the modeling process

Once the modelling is launched the output is generated automatically. The content of the document is generated automatically once the user drags and drops series into the relevant place of the document. The structure of each tramo and regarima document is the same. The results of the modelling are divided into two main parts: Input and Model and organised in a tree structure, which can be expanded. To investigate the specific node, click on it in the panel on the left to display its content in the panel on the right. Study the content of the section using the vertical scrollbar.

The modelling results

The fundamentals of the TRAMO and the RegARIMA models are the same. Therefore, the description of the output, which is presented in the subsequent sections, is illustrated with the results from the TRAMO model. However, the description is also valid for the results from the RegARIMA model.
