| 1. | 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。 |
