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.
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. And it's just as easy to exchange data and results with your spreadsheet and database programs. Unlike some other econometric software, there is no reason for most users to learn complicated a complicated command language. Hypothesis tests on mean, median and variance may be carried out, including test against specific values, equality between series, or equality within a single series when classified by other variables. Graphical presentations of histograms, cumulative distribution, survivor, and quantile plots characterize the distribution of your data.
