它的存在，本身就是一种价值，一种品质和质量的象征。 - The f value of the interaction effect on the mean score was 0 . 19 , p > 0 . 05
95 ， p均0 05 。性别和个性类型交互作用项在平均成绩上的fd - Author used spam assassin corpus to test teiresias algorithm and got good precision rate and recall rate and f value
在spamassassin语料上的实验表明运用该算法获得了较好的正确率、召回率和f值。 - With regard to the relationship between physique and urban - rural factors , the f value decreased significantly when family income per capita was taken as a covariate , while the f values slightly decreased also when factors of latitude etc . were taken as covariates
多因素分析讨论时，当协变量家庭人均收入投入后，体格的城乡因素的f值明显变小，而协变量自然环境因素投入后变化却不十分明显。 - 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
进一步深入分析研究发现，本文提出的这种基于主成分的神经网络预报模型，预报精度明显高于传统的逐步回归方法，其主要原因是这种新的预报模型集中了众多预报因子的预报信息，并有效地利用了人工神经网络方法的自组织和自适应的非线性映射能力；而传统的逐步回归方法是一种线性方法，并且逐步回归方法只是根据f值大小从众多预报因子中选取几个预报因子，其余预报因子的预报信息被舍弃。
