The OxMetricstm system presents an interactive menu-driven graphics-oriented system for econometric, statistic, and financial analysis. Here we describe the core OxMetrics program, which acts as the `front-end' to a series of integrated software modules. These modules obtain their data from OxMetrics and return output and graphics to it. OxMetrics is the component that allows you to load, edit, and save data; transform that data using the calculator or algebra; create a wide variety of graphs, which can be edited, amended and saved in various formats; provide the data for other modules to analyze; receive their text output, results, and graphics; and lets you edit, amend, and save any or all of these as desired. As such, the OxMetrics front-end can be seen as the desktop for econometric and statistical modelling.
