Abstract

This paper investigates the role of the weight function in the quality of the High Dimensional Model Representation's (HDMR) truncations at different levels of multivariance. This is done by evaluating the additivity measurers at different levels of multivariance, for specified weight functions and targets for HDMR. The observations imply that the weight functions picking function values from regions where the addive nature of the target function dominates.
