A New Kind of User Interface

The goal in designing EViews was to make it both powerful and intuitive. A wide range of statistical and graphical techniques had to be made available without requiring users to memorize complicated command syntax or navigate layers and layers of menus. The solution is an innovative object-oriented user interface.

EViews is built around the concept of objects. Series, equations, and systems are just a few examples of objects. Each object has its own window, its own menus, its own procedures, and its own views of its data. Most statistical procedures are simply alternative views of the object. For example, a simple menu choice from a series window changes the display between a spreadsheet, line and bar graphs, a histogram-and-statistics view, a correlogram, and a unit root test. 

Similarly, an equation window allows you to switch between a display of the equation specification, basic estimation results, the coefficient covariance matrix, graphics depicting the actual, fitted, and residual values for the dependent variable, tables, forecast graphs and evaluations, and more than a dozen diagnostic and hypothesis tests. 


Naturally, you can cut-and-paste any of these views into your favorite word processor with a simple menu selection. And it's just as easy to exchange data and results with your spreadsheet and database programs. Of course if you don't like cut-and-paste, EViews supports direct file access to Lotus WKS, WK1, and WK3 files, Microsoft Excel XLS files, and Microsoft Windows Metafiles.
