N2 - We deduce relationships that are implied by the color-evaporation model CEM between the nonperturbative NRQCD matrix elements that appear in the factor-ization formula for quarkonium production. These relationships are at odds with the phenomenological values of the matrix elements that have been extracted from the Tevatron data for charmonium production at large transverse momentum. A direct comparison of the CEM and NRQCD factorization predictions with the CDF charmonium production data is discussed.
