Resumen

We introduce the "Sequential Empirical Bayes Method", an adaptive constrained-curve fitting procedure for extracting reliable priors. These are then used in standard augmented-chi-square fits on separate data. This better stabilizes fits to lattice QCD overlap-fermion data at very low quark mass where a priori values are not otherwise known. We illustrate the efficacy of the method with data from overlap fermions, on a quenched 16³ × 28 lattice with spatial size La = 3.2 fm and pion mass as low as ∼ 180 MeV.
