Invocation

To start the program from the jar file, type java -jar reggui.jar or java -classpath reggui.jar regress.RegGUI, to start it from the compiled sources, type java regress.RegGUI.

The dialog box contains five tabs, three of which correspond to the command line programs dom (domain determination, contained in the table package) mpr (multivariate polynomial regression induction), and mpx (multivariate polynomial regression execution, both contained in the MPR package).

Data Format

On the first tab the format of the data file can be specified:
(Note that this tab is not executable.)

It is assumed that a data file consists of several records, each of which contains several fields (but all records have the same number of fields). As their names indicate, record separators separate records and field separators separate fields within a record. Blanks are characters that are used only to fill fields, for example to achieve a certain width, so that fields of different records are aligned in a text editor. They are removed when the file is read for processing.

By default it is assumed that the first record of the data file contains the names of fields. If this is not the case, the corresponding box should be unchecked, so that default names (field numbers, starting with 1) are generated.

Domain Determination

With the second tab attribute domains can be determined:

The regression model induction program needs as input a description of the domains of the attributes. This tab serves the purpose to generate such a domain description from the data file, which is done when this it is in front and the "execute" button is pressed. The attribute types are determined automatically if the corresponding box is checked. This may fail: If a nominal attribute has numbers as values, which have no numeric meaning, the program will still assume that the attribute is numeric. To correct such things the generated domain file has to be edited. This can be done by pressing the Edit button, which opens a simple text editor.

This tab also lets you locate the underlying programs if they cannot be found through the "path" environment variable. If you place the programs into the same directory where you start this graphical user interface, locating the programs should not be necessary.

If the external C programs are not available, the program is able to perform the same operations based on internal Java routines, which is done if the box "Use external programs" is unchecked (default).

Induction

With the third tab a regression model can be induced:

Execution

With the fourth tab a regression model tree can be executed on a data set:
