3.11. Building a field tree

Click the Analysis>Clustering>Build field tree command to open the "Tree calculation setup" dialog box from where you can define the parameters for building a field tree for the current table.

1. The "Fields" button that calls the "Field selection" dialog box. 2. List of correlation coefficients. 3. List of distance types. 4. List of amalgamation rules. 5. The "OK" button that starts creating a tree. 6. The "Cancel" button the cancels building a tree.

3.11.1. The "Fields..." button opens the "Field selection" dialog box (see section 3.3). At the right of this button, you can see the number of selected fields.

3.11.2. The "Correlation type" list contains the following three correlation coefficients:

3.11.3. The "Distance type" list includes three types of distance measures calculated from the Rij correlation coefficients:

3.11.4. The "Amalgamation rule" list has the following four types of tree node combination:

Note. If no fields were selected, the "Error" information box will appear on your screen (Fig. 3.11.2). When the calculation is in progress, you will see the "Please wait" information box (Fig. 3.11.3). This information box will disappear after the calculation is complete.
