The Drill Down

In another example, a large industrial catalog initially was skeptical that statistical modeling would outperform its own intensive testing methods (it had tried it before, without positive results). It turned to a different vendor for a fresh perspective.

The new model that was created accurately predicted the best- and the worst-response segments with a nearly perfect ranking. In addition, the top-half segments outperformed the bottom-half segments significantly. Models subsequently have been developed for other product lines showing similar results in predictability.
