    Softpedia Editor's Review for gretl

    EDITOR'S RATING:

    Econometric analysis made easy

    Written by Elena Opris on April 8th, 2013

    gretl is a software tool developed for users who frequently work with econometric analysis, by providing them with a bunch of useful features.

    The interface of the program is represented by a common window where you can import sample files (Gretl, Greene, Ramanathan), user files, as well as import various items or append data, such as CSV, TXT, SPSS and SAS.

    Creating a new data set can be done by specifying the number of observations and data set structure (cross-sectional, time series, or panel).

    It is possible to show data set values, get summary statistics, build a frequency distribution or box plot, edit attributes and values, as well as to add a log and to define new variables.

    A multitude of tools are available through gretl. For instance, you can create statistical tables and distribution graphs, find a p-value, plot a curve, run nonparametric tests and set a seed for random numbers. 

    Furthermore, you can locate a particular variable, define or edit data lists, add your own observations, export the variable labels to an external file, and transpose or sort data, just to name a few. There are dozens more options available in this program.

    gretl runs on a low-to-moderate amount of CPU and system memory, so it shouldn't interfere with the runtime of active processes. It is very responsive to key strokes and mouse events, and includes a complete user manual. We have not encountered any problems in our testing; gretl did not hang, crash or pop up error dialogs. On the downside, the interface is not very user-friendly. To sum it up, gretl should please all users who prefer a wide range of tools and configuration options when dealing with econometric analysis.

    gretl description

    Here are some key features of "gretl":

    · Easy intuitive interface (now in French, Italian, Spanish, Polish, German, Basque, Portuguese, Russian, Turkish and Czech as well as English)
    · A wide variety of estimators: least squares, maximum likelihood, GMM; single-equation and system methods
    · Time series methods: ARMA, GARCH, VARs and VECMs, unit-root and cointegration tests, etc.
    · Output models as LaTeX files, in tabular or equation format
    · Integrated scripting language: enter commands either via the gui or via script
    · Command loop structure for Monte Carlo simulations and iterative estimation procedures
    · GUI controller for fine-tuning Gnuplot graphs

    What's New in This Release: [ read full changelog ]

    · Officially increase the maximum length of variable names to 31 characters
    · "foreign" command: add support for Python + NumPy
    · "markers" command: add support for the panel-data case where the number of markers equals the number of cross- sectional units
    · "delete" command: add option to delete all variables of a specified type
    · "qlrtest" command: compute asymptotic p-value as per Bruce Hansen's method (1997)
    · "modeltab" command: add --output option to direct the model table to a specified file
    · $xlist accessor: make available for system estimators
    · You can now use "bundle b = null" to create a new bundle or empty an existing one
    · Enable more streamlined syntax for setting and accessing objects within bundles, as in bundle.member
    · Add new string function strstrip()
    · Add new data-manipulation function aggregate()
    · Add new function quadtable(), for Gauss quadrature
    · Add new function remove(), for file deletion
    · lags() function: add an optional third parameter to control the ordering of te...
