| Abstract: | The theory of Bootstrap method and the Bayes Bootstrap method and the application of the two methods in the small sample are studied. The paper analyses the principle of the two methods and gives two estimation methods, namely, the point estimation and the interval estimation to reckon unknown parameters in population distribution. It implements the simulation of Bootstrap method and Bayes Bootstrap method by means of non-parameter sample and by compiling C language. By analyzing an example, it presents the concrete errors of the shot system warp under the Bayse Bootstrap method, the Bootstrap method and the classic statistics method. The conclusion is that the Bayes Bootstrap method is better than the other two methods. |
