  1. Considering the one - sidedness and inaccuracy of knowledge discovery only from single - color database, an approach is proposed to discover knowledge from 1331 groups of mix - color database with partial least - square regression, based on measuring and learning 400 groups of single - color database. by this method, the mean error decreases when converting from rgb to cmyk, the precision of color matching is improved, and the automatic and general problem in color matching is further solved

    本文基於統計學習理論構造了一種快速自適應隨機搜索演算法，證明了演算法的收斂性.給出了一種簡易實用的寬帶天線匹配設計新方法.應用該自適應演算法進行天線匹配設計，不僅演算法簡單，易於編程實現;而且能夠快速設計出具有較好性能的匹配網路，非常適用於各種短波、超短波天線的匹配設計問題
  2. Based on the principle of the cooperation, i. e, the correlative stochastic equations are located on the same probability level, the linear regression with fuzzy weight analysis is adopted to fit the test data, and the three - parameter stress - life curves of the mean and the mean square deviation are obtained

    根據協同原理，即相關聯的隨機方程動態地處于同一概率水準，採用模糊隨機加權線性回歸方法對試驗數據進行擬合，得到了三參數的應力-壽命模型均值和均方差曲線，從而求得在給定應力下各可靠度的疲勞壽命。
  3. This thesis uses the mean square error method, and it constructs the revised msb criterion. by reviewing the revised msb, we can choose the independent variables of the regression model and decrease the calculation

    以前的文獻中在考慮到模型選擇的問題時，多會應用到已有的準則，例如： aic準則， bic準則， cp準則以及逐步法。
  4. Data was analyzed by frequency distribution, mean, standard deviation, chi - square test, and stepwise regression

    對疾病所抱持的態度，則多呈正向之態度。
  5. For the regression estimation when the auxiliary variate is correlated with the disturbance, the bias and mean square error ( mse ) of the regression estimator are obtained, and the estimator of the mse is presented

    摘要討論了輔助變量與擾動項相關條件下的回歸估計，給出了在這種條件下回歸估計量的偏差和均方誤差以及均方誤差的估計。
  6. However, two - stage estimates of regression coefficients corresponding to these two estimates have approximate equal mean square error. for testing linear hypothesis about regression coefficients, banerjee and magnus ( 1997 ) studied the sensitivity of f - test sta, tistic ( fgls ( ) ) based on generalized least square estimate caused by variance parameter in general case and proposed sensitivity statistic and its distribution

    關于回歸系數的線性假設檢驗問題， banerjee和magnus （ 1997 ）在一般情況下從理論上研究了方差參數對基於廣義最小二乘估計的f -檢驗統計量（ f _ （ gls ） （ ） ）的種種影響，提出了敏感性的概念，並給出敏感統計量的形式及其分佈。
  7. The present paper gives some profound results of linear biased estimation of regression coefficients which include linear biased estimation for the minimum mean square error, the necessary and sufficient conditions for the linear biased estimation superior to least square estimation, the necessary and suffic ) ent conditions for the admissibility of linear biased estimation and some linear biased estimators not included in the literatures
