| Abstract: | How to acquire proper prior distribution is a key problem in Bayesian analysis based on small sample.Aiming at the problem of acquiring the prior distribution of strapdown inertial measurement unit(SIMU) successive test data,the fusion method of multiple prior information is discussed in the case of hetero-populations.It is proposed to apply Bootstrap dispersion method to achieve the fusion of information of multiple sources,so as to get prior distribution and posterior distribution of SIMU successive test data.The statistical conclusion based on it can reduce the errors caused by small sample statistical analysis. |
