解釋
精確估計-
If the ill - conditioning is really existence in adjustment model, we must take measures to remove or weaken its influence in order to gain good precisions of parameters estimator and adjustment production
當確知測量平差模型存在病態性時，必須設法消除或減弱病態性的影響，以提高參數估計和平差成果的精度。 -
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。 -
In order to reduce the deficiencies of ridge estimator, stein shrunken estimator and principal component estimator, two new biased estimators, so - called combining ridge and shrunken estimator, and, combining ridge and principal component estimator, are constructed respectively. their good properties in the mean squared error and the numerical value stability are investigated, the determination of biased parameter of the estimators are discussed, and some important conclusions are obtained, respectively. theory analysis and the computational results demonstrate that the two estimators potential estimator in surveying adjustment
本文針對嶺估計、 stein均勻壓縮估計和主成分估計存在的缺陷，構造了兩種新的有偏估計：嶺?壓縮組合估計和嶺?主成分組合估計，討論了兩種新估計在均方誤差意義下和數值穩定性方面的優良性質，討論了有偏估計中偏參數的選取問題，通過理論分析和算例分析說明這是兩種很有潛力的有偏估計。 -
The results of statistical simulation reveal that intraclass correlation coefficient is a good estimator of reliability, while pearson correlation coefficient over estimates the reliability in many conditions
統計模擬的結果顯示，組內相關系數是不錯的信度估計量，但皮爾遜相關系數較會有高估的情況。 -
Those prove those two method have good estimator in those situations. last bring forward some problems need improve. we can draw the follow conclusions from simulation and theoretic analysis : nonlinear observer and ins / gps system have those virtues : high estimated precision good - robustness and simple structure, convenience used to engineer, it can replace the measured value of sensors or be used to detect fault
通過理論分析和模擬驗證，我們得到如下的結論：非線性觀測器方法具有估冠穿北口二習七大學碩創七學位論文計精度高、很好抗干擾能力; ins / gps系統方法具有結構簡單，易於工程實現，實時性好;兩種方法均具有很高的工程應用價值，能夠為現有硬體傳感器提供一個解析余度信號和提高傳感器的可靠性水平。
