| 摘 要： | 本文用验前数据的质量因子及估计的相对均方误差分析了导弹最大射程的一类Ｂａｙｅｓ估计的性能，对不同的质量因子，给出了最佳验前数据量的一种近似公式。针对这类Ｂａｙｅｓ估计的冒进问题，本文对它们进行了改进并得到了一类新的估计。最后，通过ＭｏｎｔｅＣａｒｌｏ法比较了这些估计的相对均方误差，验证了新估计的优良性。

| Abstract: | In this paper, the performance of some kind of Bayes estimates for the maximum range of a missile is analysed in terms of the quality factor of the prior data and their mean square error. For the different quality factor, some approximation to the best volume of the prior bata are given. In view of the rash advance of this kind of Bayes estimates, an improvement is made for them and some new kinds of estimates are obtained. Furthermore,a comparision of their mean square error is reported by the Monte Carlo, and shows the good performance of the new estimates. |
