In the context of the CT14 analysis of parton distribution functions, we propose a new technique for generation of Monte-Carlo replica sets from Hessian eigenvector sets. The technique preserves non-negative behavior and asymmetry properties of Hessian eigenvector sets. The generated ensemble of Monte-Carlo replicas is suitable for various applications, such as Bayesian reweighting and combination of PDF ensembles.
