Abstract The availability of many variables with predictive power makes their selection in a regression context difficult.This study considers robust and Gummies understandable low-dimensional estimators as building blocks to improve overall predictive power by optimally combining these building blocks.Our new algorithm is based on generalized cross-validation and builds a predictive model step-by-step from a simple mean to more complex General Wound Care - Unna Boots predictive combinations.Empirical applications to annual financial returns and actuarial telematics data show its usefulness in the financial and insurance industries.
