Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: Embodiments of the invention are directed to systems, methods and computer program products for utilizing a shadow ridge rescaling technique to model incremental treatment effect at the individual level, based on a randomized test and control data. A shadow dependent variable is introduced with its mathematical expectation being exactly the incremental effect. Ridge regression is utilized to regress the shadow dependent variable on a set of variables generated from the test model score and the control model score. A tuning parameter in the ridge regression is selected so that the score can best rank order the incremental effect of the treatment. The final score is a nonlinear function of the test model score plus a nonlinear function of a control model score, and outperforms the traditional differencing score method.
