An Object-Based Interface

At the heart of the innovative EViews interface is the concept of an object. Series, equations, and systems are just a few examples of objects. Each object has its own window, menus, procedures, and its own views of its data. Most statistical procedures are simply alternate views of the object. For example, a simple menu choice from a series window changes the display between a spreadsheet, various graph views, descriptive statistics and tests, tabulations, correlograms, unit root, and independence tests.

Similarly, an equation window allows you to switch between a display of the equation specification, basic estimation results, actual-fitted-residual graphs and tables, a display of the equation ARMA structure (if appropriate), gradients and derivatives of the specification, the coefficient covariance matrix, forecast graphs and evaluations, and over a dozen diagnostic and hypothesis tests.

You can select a histogram view from the series-specific menu

 

Multiple Window Display

 

Unlike traditional statistics programs that support viewing only one estimation equation or graph at a time, EViews allows for simultaneous display of multiple objects, each in its own window. This true multiple window support makes it easy to perform side-by-side comparisons of series plots, hypothesis tests, equation estimates, or model forecasts developed under alternative assumptions.

Dynamic Object Updating

 

EViews incorporates the best of modern spreadsheet and relational database technology into tools for performing the traditional tasks of statistical software. The EViews object-based approach includes sophisticated linking technology that allows you to define relationships between multiple objects and external data sources. Series objects, for example, may be linked by formula to data in other series, to match merged or frequency converted data from alternate data sets, or to data from external databases. When defined in this fashion, the linked series dynamically updates its data whenever the underlying data change.

 

Similarly, an EViews model simulation object can be linked to equation or system objects so that the model specification updates automatically when the underlying equation or system is re-specified or re-estimated.

Windows Integration

 

Couple all of this with strong Windows integration, including drag-and-drop file import for over twenty popular file formats and copy-and-paste export of presentation quality graphs and tables, and you have a modern interface that allows you to accomplish, with ease, tasks that are difficult or impossible using traditional statistical software.
