There is a linearity assumption that implies a necessary condition for building statistical regression models: Each predictor variable has a linear or straight-line relationship with the target variable. A popular technique for straightening data is Tukey’s Bulging Rule (TBR). However, if the predictor-target variable relationship has a "kink," the TBR will not work. Notwithstanding kinks, TBR must be applied to each and every predictor variable, one at a time against the target variable. TBR is very time-consuming, and limited to data with a bulge, not a kink.

The purpose of this illustration is to present the GenIQ Model as a data-straightener, which is robust, powerful, and without restrictions or limitations. Moreover, GenIQ can be applied to many variables – at one time. GenIQ is automatic, and thusly a time-saver. Click the title above for a cunning illustration of this unique feature of GenIQ.
