Segmentation Tree

Known Problems

If you try to cluster more than 6 variables the tool warns you that the segmentation could reach useless results and it suggests an alternative route. You can skip this if you like. However, be warned that using too many variables at once could result in a weak analysis unless the database is large, say above 5000 input rows.

If the analysis lasts several minutes, pay attention that Excel does not collide with the screensaver. We have reported instances when the screensaver prevented Excel from completing its own operations.

Finally, creating large trees may put Excel resources under pressure and make it crash. To avoid this annoyance you can reduce the number of levels in the tree, plot one side of the tree only, and can reduce the number of levels.
