Abstract
We performed the combine fits of SLAC, BCDMS and NMC data at NLO level. The data are fitted very well with different parametrizations of higher twist contributions. The theory-based parametrizations lead to the low values of QCD parameter \Lambda^{f=4}_{\overfull{MS}} \sim 140 \pm 21 MeV (or \alpha_s(M^2_Z)= 0.103 \pm 0.002).
