| Abstract: | This paper mainly discussed the case that parameters of NHPP models were change in the software testing process. Bayesian method was constructed to change - point analysis based on GGO model. The MCMC method based on Gibbs sampling was used to simulate the Markov chain of the parameters＇ posterior distribution . Finally, using the BUGS package to simulate the software failure data Mnsa ,the results of which prove the model to be objective and valid in the change - point analiysis for software reliability. |
