Joining Results - Quick Tab

Joining (Tree Clustering)

Select the Quick tab of the Joining Results dialog box to access the options described here.

Horizontal hierarchical tree plot. Click the Horizontal hierarchical tree plot button to display a horizontal tree diagram summarizing the successive clustering of objects. Refer to Joining (Tree Clustering) Introductory Overview - hierarchical tree for a brief discussion of how to interpret the tree diagram.

Vertical icicle plot. Click the Vertical icicle plot button to display a vertical tree diagram (the vertical axis denotes the linkage distance). Refer to the Joining (Tree Clustering) Introductory Overview - hierarchical tree for a brief discussion of how to interpret the tree diagram.

Rectangular branches. Select the Rectangular branches check box to display either type of tree plot (see above) with rectangular branches. Clear the Rectangular branches check box to display the tree plot with diagonal branches, which may increase readability of the diagram for solutions with "balanced" joining structures.

Scale tree to dlink/dmax*100. Select the Scale tree to dlink/dmax*100 check box in order for the tree plot to be scaled to a standardized scale (i.e., dlink/dmax*100). If the check box is cleared, the scale will be based on the linkage distance selected on the Cluster Analysis: Joining (Tree Clustering) dialog box - Advanced tab.

Note: Depending on the current default scale value font-size setting (see Axis: scale values) the item (case or variable) labels in the tree plot may overlap or the display of some (e.g., every other or third) overlapping labels may be suppressed; in such cases, click on the labels in the graph and reduce the font size.
