Calculating bayes point estimation from sample on the condition of mean square error loss function. Calculating confidence interval by an approximate method to complete interval estimation.

本文的主要工作有：(1)解决了Beta分布参数a和b的精确计算以及均值、标准差、偏度、峰度的计算问题；(2)拟合出10余种典型分布的Beta分布的两个参数，并且采用剩余标准差评价该Beta分布的拟合精度；(3)对多种典型的光学与光电测量系统的测量分布进行了Beta分布统示表示；(4)在假设先验分布为均匀分布前提下，得到参数a和b以及均值μ和标准差σ在均方误差损失函数下的贝叶斯点估计理论计算公式；(5)利用直接抽样的Gibbs抽样算法，从后验分布中产生MCMC样本，从样本直接计算均方误差损失函数下的贝叶斯点估计，并使用一种近似方法计算其置信区间，完成区间估计。

Based on ethnology theory, sociology and other subject perspectives, starting from cases of sample questionnaire and network of college students'national consciousness, it analyzes the basic characteristics of college students'national consciousness. Then, review the historical changing track of college students'consciousness Since the reform and opening time, and analyze the obsessional factors of college students'consciousness; and then, generalize some ordinary guiding and cultivating strategies. Taking the education of outlook on nation in Guangxi University for Nationalities for an example to introduce the facilitation experience of college students'national consciousness in national institutions. This provides effective reference to guiding and cultivating college students'national consciousness.
