Abstract
The results of approximate N^3LO and detailed NNLO fits to data of the CCFR'97 collaboration are presented. We demonstrate that non-perturbative corrections to modeled by three independent procedures are shadowed by perturbative QCD effects, starting at the NNLO. Special attention is paid to revealing the role of the recently calculated NNLO corrections to the anomalous dimensions and LO corrections to the coefficient functions of odd moments of with . The related values of are extracted.
