  A nonsinglet QCD analysis of neutrino-nucleon structure function is performed
based on all the data for charged current neutrino-nucleon deep inelastic
scattering (DIS) corresponds to NLO and NNLO approximations, with taking into
account the nuclear and higher twist corrections. In this analysis, we extract
$xu_v(x,Q^2)$ and $xd_v(x,Q^2)$ valence parton distribution functions (PDFs) in
a wide range of $x$ and $Q^2$, and determine their parametrization with the
correlated errors using the xFitter framework. Our results regarding
valence-quark densities with their uncertainties are compared to the prediction
extracted using other PDF sets from different groups. We determine
$\alpha_{s}(M_Z^2)$= 0.1199 $\pm$ 0.0031 and 0.1185 $\pm$ 0.0023 with
considering the nuclear and higher twist corrections at the NLO and NNLO,
respectively, and perform a comparison with other reported results. The
extracted results regarding valence-quark distributions and the value of
$\alpha_{s}(M_Z^2)$ are in good agreement with available theoretical models.
