Applied the robust estimation theory, it is made a new improved least square method. combined the normal distribution and the laplace distribution, there is created a new distribution model uber distribution in the paper, it is improved the method of the gross location and parameter estimation and is cleared out efficiently the gross error ' s effect for dam safety monitoring model
應用抗差估計理論，提出一種抗差最小二乘改進法，結合正態分佈和拉普拉斯分佈，建立新的分佈模式? huber分佈，改進了粗差定位和參數估計的方法，有效地消除粗差對監控模型的影響。 -
The distributions studied are normal distribution, student - t distribution, skewed student - t distribution and general error distribution. besides this, considering the conditional heteroskedasticity of the time serial in financial market, apply the garch model into the estimation of var
在此基礎上，研究了證券市場上時間序列收益率波動的條件異方差性，考慮中國證券市場的風險特徵，將garch系列模型與var模型相結合，構造了基於不同分佈條件下的var模型。 -
Further analysis on the model forecast residuals indicate that the residual time series does not follow a normal distribution but rather exhibits non - gaussianity ; similarly too, the existence of persistent pattern in the error / residual structure is discernibly evident
對模型預報殘差進一步分析可知，殘差的時間序列並不服從正態分佈，而是呈現出了逆高斯分佈。同樣，在誤差/殘差結構中存在著非常明顯的固定模式。 -
And use relative fitting error to measure statistical data non - uniform error ; then introduce the method systematically of using the fuzzy comprehensive evaluation method to carry on the overall superior test of the government statistical data quality. includes the establishment of step level appraisal target system, target weight determination, calculates the factor weight in various levels, uniform test of judgment matrix, and built up the final fuzzy comprehensive evaluation model of the government statistical data quality according to the above - mentioned standard ; finally selects the partial main social economy total quantity target from chinese statistics yearbook 2003 to carry on the real diagnosis analysis : ( 1 ) confirm these social economy total quantity targets using the description statistics and the k - s inspection method to obey the lognormal normal distribution. ( 2 ) according to the two levels of inspection methods which this article proposed to carry on accuracy and the overall superior test for these social economy total quantity targets
本文首先從統計數據及質量的涵義出發，全面系統的介紹了統計數據質量的概念;其次，從研究統計數據的分佈規律入手，對統計數據準確性檢驗問題進行了探討，利用對數正態分佈檢驗對反映研究對象規模大小的統計數據的質量及異常數據進行定量檢查和識別，並利用相對擬合誤差計量統計數據的非一致性誤差;接著系統介紹了利用模糊綜合評價方法對政府統計數據質量進行整體優度檢驗的思路，具體包括建立遞階層次的評價指標體系，指標權重的確定，計算各層次中因素的權重，判斷矩陣的一致性檢驗，並根據上述標準建立了最終的政府統計數據質量模糊綜合評價模型;然後通過從2003年中國統計年鑒資料中選取部分主要的社會經濟總量指標進行實證分析: （ 1 ）利用描述統計和k - s檢驗法來驗證這些社會經濟總量指標服從對數正態分佈的規律; （ 2 ）按照本文提出的二級檢驗法來對這些社會經濟總量指標進行準確性和整體優度檢驗，從而達到綜合評價政府統計數據質量的目的;最後對這種二級檢驗法的優點和不足進行小結，提出今後應該努力改進的方向。 -
Firstly, on the basic of normal error back propagation algorithm ( bp a1gorithm ), the model was added the inertia impulse item in the updating formula for weight, and then let learning rate and inertia parameter adjust ll self - adaptively, so the improved bp algorithm ( improved bp algorithm, ibp algorithm ) formed
首先，該模型在誤差反向傳播演算法（ bp演算法）的基礎上，在網路權值更新公式中添加慣性沖量項，並對學習率和慣量因子進行自適應調整，從而形成bp改進演算法（ improvedbp演算法，簡稱ibp演算法） 。
