GAUSS Westerlund tests

Econometric package containing the library of GAUSS codes of Joakim Westerlund.

Getting Started

Prerequisites

The program files require a working copy of GAUSS 19+. Many tests can be run on earlier versions with some small revisions and users should contact eric@aptech.com for a modified library for earlier GAUSS versions.

Installing

GAUSS 20+ The GAUSS Westerlund library can be installed using the GAUSS Application Installer, as shown below:

1. Download the zipped folder westerlundlib_0.1.zip from the westerlundlib release page.
2. Select Tools > Install Application from the main GAUSS menu.
3. Follow the installer prompts, making sure to navigate to the downloaded westerlund_0.2.0.zip.
4. Before using the functions created by westerlundlib you will need to load the newly created westerlundlib library. This can be done in a number of ways:

• Navigate to the library tool view window and click the small wrench located next to the westerlundlib library. Select Load Library.
• Enter library westerlundlib in the program input/output window.
• Put the line library westerlundlib; at the beginning of your program files.

Note: I have provided the individual files found in westerlundlib_0.2.0.zip for examination and review. However, installation should always be done using the westerlundlib_0.2.0.zip folder from the release page and the GAUSS Application Installer.

Examples

After installing the library the example files will be found in your GAUSS home directory in the directory pkgs > westerlundlib >examples. The example uses GAUSS datasets included in the pkgs > westerlundlib >examples directory.

Documentation

We have not yet developed detailed documentation about the library. However, you can find more information about the functions by looking at the function headers in the .src codes.

You can access these source codes through the library tool by expanding the westerlundlib.lcg menu and clicking on the file name. The file will open in the program editor and you will be able to view the headers for each specific function.
