in the paper, we analyze an estimated problem of normal mathematical expectation with unilateral interval information been met in practical work of survey, using bayes statistic approach, we get bayes estimation of normal mathematical expectation 本文对实际测量工作中遇到的一类带有单侧区间信息的正态均值的估计问题进行了分析,运用贝叶斯统计方法,得到了正态均值的贝叶斯估计。
therefore, study on road traffic safety certainly has great value 。 the paper studies three aspects of contents, including dividing road cell, developing safety level evaluation model and developing bayes statistic ? road safety evaluation method 因此,进行道路交通安全研究必将具有重要的现实意义。论文研究工作包括划分道路单元、建立安全水平评价模型和建立基于贝叶斯统计的道路安全评价方法。
secondly, revise factor coefficient with probability distribution, which given by experienced experts . thirdly, use bayes statistic deducing method to bind together the income rate of prior distribution and sample in formation, which makes forecast stocks in shenzhen stock market as samples . work out the series of weakly income rate (2)对多元回归的因子模型的各因子权重重做修正,将一些对金融市场有较透彻了解和丰富经验的专家提供的信息引入,作出因子系数的概率分布(并非随意的主观臆造),对模型的结果加以修正,以便提高模型的准确度。
in the second chapter, we explicate the theoretical knowledge, bayes statistic approach, which be applied in the paper, we show the definition of the prior distribution and how to select the prior information, we show the relation of prior distribution, conditional distribution and posterior distribution, we also show statistical inference approach and the key of how to use bayes statistic approach 第二部分内容是本文应用理论知识的简要阐述,介绍了贝叶斯统计方法的理论,分别说明了先验信息的定义及如何获取,后验分布、条件分布和先验分布三者关系,统计推断方法及贝叶斯统计方法应用的关键。第三部分内容是对坦克射击学中外弹道学的修正理论作了简要的介绍。
