An Investigation of Uncertainties in the QCD NLO Predictions of the Inclusive Jet Cross Section in pbarp Collisions at sqrt(s) = 1.8 TeV and 630 GeV

Uncertainties in the NLO calculation of the inclusive jet cross section due to the choice of renormalization scale, parton distribution functions and clustering algorithm are explored. These are found to be similar in size to the current experimental uncertainties of the measured inclusive jet cross section at DZero and CDF.
