Gestats calibrates the parameters of economic models used in Gemodel 3.2. The user enters variable values in spreadsheets where input, output, and income flows are recorded. The user also supplies some elasticity assumptions by similar spreadsheet entries. Gestats then checks the internal consistency of the data and, if no discrepancies are found, creates a file suitable for input to Gemodel 3.2. No computer programming is required from the user to process economic data in Gestats. A user's manual is included in that for Gemodel 3.2. Sample data and calibration results are included as a model of the Canadian economy.
