Abstract
Deep inelastic scattering data on structure function from various fixed-target experiments were analyzed in a nonsinglet approximation in the MSbar and DIS scheme. The study of high statistics deep inelastic scattering data provided by BCDMS, SLAC and NMC collaborations, was carried out using a combined analysis. The application of the DIS scheme leads to the resummation of contributions that are important for large x values. It is found that using the DIS scheme does not significantly change the strong coupling constant itself but does strongly change the values of the twist-four corrections.
