Query: Parton Distribution Function Uncertainties   We present parton distribution functions which include a quantitative
estimate of its uncertainties. The parton distribution functions are optimized
with respect to deep inelastic proton data, expressing the uncertainties as a
density measure over the functional space of parton distribution functions.
This leads to a convenient method of propagating the parton distribution
function uncertainties to new observables, now expressing the uncertainty as a
density in the prediction of the observable. New measurements can easily be
included in the optimized sets as added weight functions to the density
measure. Using the optimized method nowhere in the analysis compromises have to
be made with regard to the treatment of the uncertainties.
