We extract the power corrections to the {open_quotes}scaling{close_quotes} proton structure function F{sub 2}(x,Q{sup 2}) by using QCD moments obtained from the world{close_quote}s inclusive lepton-proton scattering data. As opposed to previous analyses, we take particular account of data at large Bjorken x(x{gt}0.75) which are dominated by nucleon resonances and which make up most of the structure function at low Q{sup 2}(Q{sup 2}{le}4 GeV{sup 2}). We discuss possible improvements on the determination of the magnitude of the higher twist coefficients that could be obtained from a new set of measurements of the nucleon structure functions at large {ital x} and moderate Q{sup 2}. {copyright} {ital 1999} {ital The American Physical Society}
