Bard, nonlinear parameter estimation, academic, new york, 1974 isbn. Frequentist probabilities are long run rates of performance, and depend on details of the sample space that are irrelevant in a bayesian calculation. In conclusion, we have shown that the bayesian model is a powerful tool for inference about the genetic population structure.

Within this framework, we address the problems of whether and how a particular genetic variant act on the phenotype of interest by bayesian testing and model. The general bayesian approach applied here is very flexible, and it would be valuable to incorporate information from phenotypes, different mutation models, spatial distances, and demographic parameters in the future.
