Examples
- Methods according to the bayesian conjugate prior distribution principle , the estimating methods of prior parameters ( , ) of the conjugate beta distribution be ( , ) of the binomial distribution was given by writing the sas programs
方法根据贝叶斯共轭先验分布原理，对二项分布的共轭贝塔分布中的、两个先验参数的确定方法进行分析比较，编写sas程序确定先验参数。 - Secondly , by characteristic statistic , the probabilistic distribution of silt indexes is roughly learned , then the normal and beta distribution probabilistic models are fitted for generally symmetric distribution indexes , and the beta distribution models for all indexes owing to their good adaptability . after tested , the indexes of cuu and < t > m fitted by the beta models are very good
其次，用特征统计量对粉土工程性质指标的概率分布作了粗略了解后，对大致对称分布的指标作了正态分布和beta分布拟合，对不对称分布的指标作了beta分布拟合，最后得出用beta分布拟合c _ ( uu )和_ ( uu )是较理想的。 - The class of distributions includes the weibull , burr - type x , pareto and beta distributions . a proper general prior density function is suggested , and predictive density functions are obtained in one - and two - sample cases when the history sample is a type ii double censored sample . illustrative examples are given
在type双删失数据场合下，讨论了双参数burr - type分布参数的贝叶斯估计，在所取的损失函数分别为平方损失， linex损失，熵损失函数下得到了参数的贝叶斯估计，并且给出一种近似算法。 - In the sense of mean squares , maximum likelihood estimator , best linear unbiased estimator , taest linear invariant estimator , and good linear estimator are contracted . fourth , proposed and researched the reliability analysis method under the zero - failure data and doof data . based on the part beta distribution as the prior distribution of failure probability p , = p ( t < r , } , hierarchical bayesian estimate method was discussed , obtain the reliability analysis method under the zero - failure data and the doof data
第四，提出并研究了无失效数据类型和doof数据类型下电连接器的可靠性分析方法，提出了以不完全beta分布为一级先验分布，超参数为[ 0 ， 1 ]上的均匀分布作为失效概率先验分布的多层bayes方法，结合加权最小二乘法解决了产品在无失效数据和doof数据下的可靠性分析问题。
