The BACON Visual Basic demonstration

1. Select the XML data file by using the ListBoxes provided in the upper half of the form.
2. Load the data by clicking the "Load Data" button.
3. Click on the "Set Options" button, and a dialog with the following options will be shown:
1. Alpha Value: This is the rejection level.
2. C Value: This specifies the initial subset of good data. The number of records in the initial good data set is C*m, where m is the number of variables in the data.
3. Variables and Selected variables: All the variables in the data file are shown in the left hand ListBox. The selected variables are shown in the right hand ListBox. Variables can be added to the right hand ListBox by using the mouse to select variables from the the left hand list and then clicking on the button labelled ">>". Variables can be removed from the right hand list by selecting them with the mouse and using the button labelled "<<".
4. Weight Variable: It is possible to specify a weight variable that provides the weight to be used for each record in the data file. This is achieved by using the mouse to select the appropriate variable from the right hand list and then clicking on the button labelled "Weight Variable". If a weight variable is not selected then each record is assumed to have a weight of 1.
5. "Use EM" CheckBox: If this option is selected then the BACON-EM method is used, otherwise the BACON method is used; for more details see Beguin and Hulliger, EUREDIT in D.4.2.1 and D.5.2.1.
4. Click on the button labelled "Load options" to store the selected data processing options.
5. To process the data click the button labelled "Find Outliers"
6. The processed data can be viewed by clicking on the "View Data" button.
7. If more processing is required, then go to step 3.
