One problem with the one step ahead prediction is the trade-oo between the noise concella-tion and the details detection. The methods proposed up to now perform a global analysis of the data and lead to missing some details (underrtting) or at the opposite including noise (overrtting). To solve this problem , we propose a preprocessing procedure inspired by… (More)
In this paper we deal with the non-parametric regression estimation problem. A method based on wavelet frames is introduced. The use of frames and wavelets yields to decompositions with interesting properties: robustness, multiresolution,: : : Finally, the approach is illustrated on a geostatics spatial approximation problem .
