解釋
方差檢定-
Based on the technical parameters, quality matter and character of polymeric materials and its products, the statistical method such as orthogonal array design, pareto diagram, histogram, significance testing, fuzzy mathematics have been used to carry out a series of study. by doing so, the inherence relationship and variance property, degree and reason of polymeric materials and its products have been obtained ; it could get better improved by adopting correcting measure
本論文以高分子材料及其製件的工藝參數、質量問題和質量特徵值為研究對象，利用正交實驗設計、調查表、因果圖、排列圖、直方圖、控制圖、故障樹（ fta ） 、顯著性檢驗、相關分析以及模糊數學評定法等多種統計技術方法，從不同角度進行了一系列探索性研究，得到了高分子材料及其製件內在關系及變異的性質、程度和原因，採取了糾正措施並取得了較好的效果。 -
Secondly, a ship undocking process environmental forces testing plan is made by using the orthogonal design theory. measuring the environmental forces with different wind, wave and current combination from 0 ? to 90 ? and analyzing and processing the data are finished by using the analysis of variance method. comparing the experimental results with the results calculated using the ocimf method, the reliability of using the ocimf method is testified
二、利用正交設計方法，制定了船舶出塢過程環境載荷測量方案，完成了船舶在出塢過程中從90到0過程中在不同風、浪、流組合下的環境外力測試和分析處理，利用級差分析方法，重點分析了風、浪、流以及方向對船舶出塢的影響程度大小，並把試驗結果和ocimf方法計算結果作了比較分析，驗證了ocimf方法計算結果的可靠性。 -
In the second study, the results of testing the measurement model of the health behavior scale indicated good reliability and accounted for a large amount of variance
第二個研究是做健康行為量表整個量測模式的檢定，結果顯示本量表具有良好的信度，且能解釋大的變異量。 -
The present methods for testing the large - scale corpus segmentation have the following faults : a. it is difficult to exactly estimating the variance of population ; b. the sampling quantity is too large to test the corpus segmentation. to solve the given problems, we put forward the testing method based on clustering, which sorts the sample of corpus into many group by clustering them
語料庫分詞質量的評價問題是漢語語料庫的特有問題，已有的簡單隨機抽樣的方法，當語料庫規模變大時，無法精確估計分詞質量評價中語料庫樣本的總體方差，同時，為了保證檢驗的精度，傳統抽樣方法的檢驗費用太高。 -
The following merits can gain by using the clustering method : a. the sampling quantity can be reduced by using the method to test the segmentation of the large - scale corpus ; b. the testing precision can be improved and the variance of population can be estimated more exactly
與已有的簡單隨機抽樣方法相比，本文提出的方法在大規模語料庫分詞質量評價時，有如下優點； a通過聚類得到語料庫抽樣樣本分詞正確率的分層知識，進而在檢驗中運用分層抽樣帶來的增益減少檢驗的費用： b -
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。 -
The analysis of how the training model influenced the students " thinking ability, creativity and study performance is done by using a few statistical methods including analysis of double samples " variance, supposition of double sampling, testing of significant difference
運用雙樣本方差分析，雙樣本假設、差異顯著性檢驗等幾種統計方法，分析了六階段思維策略訓練的課堂操作模式對學生思維能力、創新意識、學習成績的影響。
