| 摘要: |
| 研究了考虑验前信息可信度时的验前分布和Bayes估计算法，给出了正态总体参数的Bayes估计方法。以导弹落点散布的估计为例，说明了考虑验前信息可信度时Bayes估计有明显的改善，即具有更好的可信度。 |

| Abstract: |
| By considering the credibility of the prior information, a new Bayesian estimation algorithm is studied, and the estimation of normal distribution parameters is provided. Taking the estimation of the dispersion of the missile falling points as an example, the conclusion is drawn that by considering the credibility of the prior information, the new algorithm of Bayesian estimation is obviously improved,that is, it is of a better credibility. |
| Keywords: Bayesian estimation prior information confidence level dispersion of the missile falling points |
