At large values of $x$, the parton distribution functions (PDFs) proton are poorly constrained and there considerable variations between different global fits. Data at such high $x$ have already been published by ZEUS Collaboration, but not yet used in PDF extractions. A technique for comparing predictions based on sets to observed number events data is presented. It applied compare from most commonly PDFs Bjorken $x$. wide variation found ability predict results. scheme including high-$x$...
