  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，提出並研究了無失效數據類型和doof數據類型下電連接器的可靠性分析方法，提出了以不完全beta分佈為一級先驗分佈，超參數為[ 0 ， 1 ]上的均勻分佈作為失效概率先驗分佈的多層bayes方法，結合加權最小二乘法解決了產品在無失效數據和doof數據下的可靠性分析問題。
  2. Best asymptotically normal estimator

    最佳漸近正規估計量
  3. Regular best asymptotically normal estimator

    正則最佳漸近正態估計量
  4. Abstract : the generalized shrunken prediction of finite population is introduced, using generalized shrunken least squares estimator of linear regression models. with respect to prediction mean squared error, a necessary and sufficient condition for superiority of a generalized shrunken prediction over the best linear unbiased prediction is obtained. in the case of linear combination of every unit index, a linear restricting prediction is introduced and then a necessary and sufficient condition for superiority of linear restricting prediction over the best linear unbiased prediction is devived

    文摘:利用線性回歸模型的廣義壓縮最小二乘估計，引入了有限總體的廣義壓縮型預測，在預測均方誤差意義下，得到了廣義壓縮型預測優于最佳線性無偏預測的一個充分必要條件；在只能得到每個個體指標的線性組合時，引入了一種線性約束型預測，並得到了線性約束型預測優于最佳線性無偏預測的一個充分必要條件
  5. The maximum likelihood estimator ( mle ) approach is an important one in frequency estimation domain. this approach has the merit such as exhibiting best performance and requiring minimum threshold of signal noise ratio in calculation

    最大似然頻率估計法是該領域中的一種重要的研究方法；該方法具有估計結果準確，計算所要求的信噪比門限值低等特點。
  6. Abstract : to settle the numbers of groups, the moth and features of group sampling are analysed, and its estimator is goven. then using cauchyschwartz unequility, it seeks the best apportion with finite cost

    文摘:為了確定分類抽樣的各類單位數，分析了分類抽樣的抽取方法和特點，同時給出其簡單估計，然後利用柯西-施瓦茨不等式推導出在給定調查費用情況下的最優分配
  7. Based on wavelet analysis, wls is the best linear unbiased estimator of regression model parameters in the context of l / f noise
