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。 -
Chapter 5 is focused on the studies on the equivalent conditions for maximum value convergence of sums of independent random matrix sequences, and the sufficiency condition of the strong consistency of m estimator of regression parametric in linear model for negatively associate samples, thus enriching and strengthening the results of a series of papers
第五章得到了獨立陣列和（含加權和）的最大值完全收斂的等價條件，從而豐富和強化了前人的一系列結果獲得了負相關樣本線性模型中回歸參數m估計是強相合的較弱的充分條件 -
The results indicate that if all the investors all full rational, the equilibrium price, whether using close call auction or open call auction, is the unbiased estimator of the risky assets true value
研究結論表明，若所有的投資者都是理性的，無論採用封閉式集合競價還是開放式集合競價，那麼均衡價格均是風險資產真實價值的無偏估計量。 -
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。 -
Two kinds of risk measures are considered, volatility and value at risk ( var ). some methods based on our local polynomial estimator and some other recent work to calculate the volatility based on discrete observations are given. a time dependent value at risk ( tvar ) based on stochastic processes is defined
我們主要考慮金融風險度量的兩種方法，一是波動率，我們給出了一些基於離散觀察的波動率的計算方法；二是在險值（ var ） ，我們定義了一種基於隨機過程的在險值，稱為時變在險值
