Bootstrap center fusion estimation of prior distribution of SIMU successive test data

It is a key problem in Bayesian analysis about small sample how to get proper prior distribution. Aiming at the problem that how to get the prior distribution of strapdown inertial measurement unit (SIMU) successive test data, the fusion of multiple prior information is discussed in the case of hetero-populations. Bootstrap center method is used to achieve the fusion of multiple-hetero-population, in order to get prior distribution. It can reduce the error of statistical analysis under the condition of small sample.
