  1. Through the simulation and error comparison between classics regression model and neural network model, it showed that bp should be applied in liquid concentration measurement system to improve measurement accuracy and decrease the non - linear effect from temperature

    通過模擬研究,與傳統的回歸模型進行誤差對比,得出了應採用bp神經網路技術建立智能化液漿濃度測量模型,提高測量精度,克服溫度變化非線性影響的結論。
  2. ( 2 ) when analyzing the testing method for the " day - of - week effect ", we considered the ols regression effect and the testing power will decrease because of the different variable in real securities data. we considered the identification. estimation and hypothesis testing of the linear regression model with one rank auto - regression ( ar ( 1 ) ) error ( 3 ) we considered how investors reasonably utilize the testing result of the " day - of - week effect " to direct the investment strategies after obtained it

    ( 2 )在對「周內效應」的檢驗方法進行分析時,考慮到實際證券數據由於具有異方差性,使得利用ols進行回歸將導致回歸效果和檢驗的勢降低,我們對于具有一階自回歸誤差的線性回歸模型,仔細討論了該模型的識別、估計和對相應參數假設檢驗的方法。
  3. Evidence suggests that the prognostic ability of the new model with high stability, when hidden nodes changing nearby input nodes and training times changing at the certain extent, is significantly better than traditional step wise regression model mainly due to the new model condensing the more forecasting information, properly utilizing the ability of ann self - adaptive learning and nonlinear mapping. but the linear regression technique only selects several predictors by the f value, many predictors information with high relative coefficients is not included. so the new model proposed in this paper is effective and is of a very good prospect in the atmospheric sciences fields

    進一步深入分析研究發現,本文提出的這種基於主成分的神經網路預報模型,預報精度明顯高於傳統的逐步回歸方法,其主要原因是這種新的預報模型集中了眾多預報因子的預報信息,並有效地利用了人工神經網路方法的自組織和自適應的非線性映射能力;而傳統的逐步回歸方法是一種線性方法,並且逐步回歸方法只是根據f值大小從眾多預報因子中選取幾個預報因子,其餘預報因子的預報信息被舍棄。
  4. One of the important hypotheses of classical linear regression model is that the random disturbances have equal variance

    經典線性回歸模型的一個重要假設就是回歸方程的隨機擾動項u _ i ,具有相同的方差,也稱同方差性。
  5. A linear multi - regression model as thus made in the end, the authors flied to predict the current and quantity of the farmland change

    並在此基礎上,建立多元線性回歸模型,對安徽省耕地變化的趨勢進行科學的預測。
