f-test meaning in English
f检验
Examples
- Our simulation results show that for high positive errors correlation cases , these new tests have lower type - 1 error and large power than modified f - test
模拟结果表明，当误差正相关程度较高时，两种新检验在具有较小的第一类错误概率的同时，具有较大的功效。 - In this paper two new test statistics by using matching the first three moments approach are proposed to approximate fgls ( ) by x2 and f variables . a comparison with modified f - test by wu et al ( 1988 ) is completed
本文用“前三阶中心矩相等”法，提出了两种新检验，分别用卡方统计量和f统计量去逼近( f _ ( gls ) ( ) ) ，并与wu ， holt和holmes ( 1988 )提出的修正f检验进行了比较。 - By using quantitative ( f - test , correlation analysis and questionnaire ) and qualitative ( interview ) research methods , we observed the teaching of immersion musical appreciation and it ' s results concerning children , teachers and parents . the followings are the results we obtained : in respect to children : the immersion teaching method : l . to made imagine and abandon . 2 . deepened their impression of music 3
论文运用定量(音乐能力测验的方差分析、相关分析和问卷调查)和定性(访谈、课堂观察)的研究方法，对幼儿音乐浸润式欣赏教学进行分析、研究，发现在短短地3个月时间里，教学取得了令人惊喜的效果。 - The pca results indicated that the characteristics of length , breadth , the angle of leaf basal in lamina and the characteristics of calyx - tube , corolla dimension and inflorescence pedicel in the flower were the main reasons leading to the morphological variations , and the f - test of single factor variance analysis verified the conclusion
主成分分析显示，叶部特征的长度、宽度、叶基夹角等，以及花部特征的花兽筒、花冠幅、花序总梗等是造成不同居群野生早樱表型差异的主要因素，单因素方差分析也印证了这一结论。 - 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
关于回归系数的线性假设检验问题， banerjee和magnus ( 1997 )在一般情况下从理论上研究了方差参数对基于广义最小二乘估计的f -检验统计量( f _ ( gls ) ( ) )的种种影响，提出了敏感性的概念，并给出敏感统计量的形式及其分布。
