Researches on the Method of Bayesian Models Selections and Averages
For improving the analyses results of Bayesian model selections and averages, by which the uncertainties and risks of analyses results of natural disasters can be reduced or removed, two important problems about Bayes Factors computation, i.e. determination of parameters prior distribution and numerical integration of models, are mainly discussed and resolved firstly, then a new method of Bayes Factors computation has been proposed, finally the accuracy and effectiveness of this new method have been confirmed and compared with BIC by Monte-Carlo tests. Results show that the new method is more effective and reliable than BIC, since it can overcome the influence of many unfavorable factors by analyzing and describing the uncertainties of models parameters.
