Abstract

Polynomial spline regression models using B-spline basis functions are shown to provide greater flexibility and lead to more accurate predictions than traditional polynomial models. Use of multifactor B-spline regression models is described in a case study from the automotive industry in engine mapping using a two-stage hierarchical model. The accuracy and effectiveness of the approach is demonstrated with validation runs.
