Specifications may include polynomial lag structures on any number of independent variables. Weighted estimation is available with all of these techniques. Basic estimators include ordinary least squares (multiple regression), two-stage least squares and nonlinear least squares.
CROSS CORRELOGRAM EVIEWS SERIES
These may be used in generating new series as well as scalar and matrix expressions.ĮViews includes a wide range of single and multiple equation estimation techniques for both time series and cross section data. Unit root tests (ADF and Phillips-Perron), cointegration tests, causality tests, autocorrelation and partial autocorrelation functions, Q-statistics, and cross-correlation functions, let you explore the time series properties of your data.ĮViews provides random number generators, density functions and cumulative distribution functions for seventeen different distributions. EViews also calculates kernel density estimates, and produces scatterplots with curve fitting using ordinary, transformation, kernel, and nearest neighbor regression. QQ-plots (quantile-quantile plots) compare the distribution of a pair of series, or the distribution of a single series against a variety of theoretical distributions. Graphical presentations of histograms, cumulative distribution, survivor, and quantile plots characterize the distribution of your data. 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. EViews' built-in procedures are a mouse-click away and provide the tools most frequently used in practical econometric and forecasting work.īasic descriptive statistics are easily computed over an entire sample, by categorization based on one or more variables, or by both cross-section and period in pooled data. Unlike some other econometric software, there is no reason for most users to learn complicated a complicated command language. Of course, programming isn't for everybody.
CROSS CORRELOGRAM EVIEWS WINDOWS
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. And it's just as easy to exchange data and results with your spreadsheet and database programs. Naturally, you can cut-and-paste any of these views into your favorite word processor with a simple menu selection. 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.
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. Most statistical procedures are simply alternative views of the object. Each object has its own window, its own menus, its own procedures, and its own views of its data. Series, equations, and systems are just a few examples of objects. The solution is an innovative object-oriented user interface.ĮViews is built around the concept of objects. 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 goal in designing EViews was to make it both powerful and intuitive. Designed for the new generation of 32-bit Windows operating systems, and featuring major enhancements to both data management and modeling tools, EViews 3.1 continues to set the standard for econometric and forecasting software. The combination of power and ease-of-use made EViews an immediate best seller.įour years later, QMS is pleased to announce the release of EViews 3.1.
CROSS CORRELOGRAM EVIEWS SOFTWARE
Featuring a modern, graphical object-oriented user interface, EViews provided an alternative to antiquated, software design. In March of 1994, QMS launched a revolution in econometric software with the release of EViews 1.0.
