We present unpdate to the Bodek-Yang model for inelastic neutrino- and electron-nucleon scattering cross sections using effective leading order parton distribution functions with a new scaling variable xi_w. Non-perturbative effects are well described using the xi_w scaling variable, in combination with multiplicative K factors at low Q^2 for Q^2 < 1 GeV^2. Our model desribes all inelastic charged lepton-nucleon scattering (including resonance) data (HERA/NMC/BCDMS/SLAC/JLab) ranging from very high Q^2 to very low Q^2 and down to the photo-production region. The model describes existing inelastic neutrino-nucleon scattering measurements, and is currently used in analyses of neutrino oscillation experiments in the few GeV region.
