Using the Model via the Graphical User Interface

The graphical user interface (GUI) to the MYI-Tax-Analyzer CLI guides you through the specification of a model run (automatically generating a run specification file), executes the run, and provides easy viewing of all resulting text output and graphs in your default web browser. And, as described below, there is a command-line tool myigds that automates the preparation of Growdiff statements.

Start the GUI using the myigui tool, and read the Help page to understand the GUI workflow.

The GUI is organized as a notebook in which each page is accessed by clicking on its tab.

When on the Run notebook page on a Mac computer (running MacOS Big Sur), the GUI appears as shown below. On a Windows computer the GUI would have the look and feel of a native Windows application.

Using the myigds tool

The myigds command-line tool prepares the Growdiff statements that correspond to a projection of the annual levels of macroeconomic variables that differs from the baseline projection built into the model. An alternative projection is in a four-row CSV-formatted file that typically would be generated in the spreadsheet program where the alternative projections are being developed. After executing the myigds tool, the Growdiff run-specification-language statements implied by the alternative projection are on the GUI clipboard and can be included in the Growdiff Code Box by clicking on the Paste-Lines button on the GUI Growdiff page. Execute the myigds --help command to get more information.
