  We apply analytic perturbation theory to the QCD analysis of the xF_3
structure function data of the CCFR collaboration. We use different approaches
for the leading order Q^2 evolution of the xF_3 structure function and compare
the extracted values of the parameter Lambda_QCD and the shape of the higher
twistcontribution. Our consideration is based on the Jacobi polynomial
expansion method of the unpolarized structure function. The analysis shows that
the analytic approach provides reasonable results in the leading order QCD
analysis.
