Empirical Baye's Method and Test in Very Light Quark Range from The   Overlap Lattice QCD
  Based on Bayesian theorem an empirical Baye's method is discussed. A programming chart for mass spectrum fitting is suggested. A weakly constrained way for getting priors to solve the chiral log data fitting singularity is tested.
