查询词典 regression coefficient

The patient's rating was then dichotomized and fitted in a multiple logistic regression. After controlling for the hospital accreditation levels, patient's diagnosis, and patient's education level in the regression model, we found that the percentage of nurses with bachelor degree, years of clinical experience, and total nursing hours were significantly and positively associated with patient's ratings.

在双变项分析中，护理师比例与大学学历以上比例具高度相关，为了避免「共线性」的问题，最后选择大学学历以上比例纳入多变项分析；最后以病人评分高低为依变项进行逻辑斯回归，在控制医院评鉴等级、病人疾病诊断别、以及病人教育程度后，结果显示护理人员大学学历以上比例、平均临床工作年资及急性病房护理时数，对病人观点照护品质评分均呈现显著正向影响。

As there were too much description between mathematic model and practice, many useful information was lost duding regression, the regression could not give satisfied results in color style research. The research on color style provided a new field in textile and clothing. This study provide the basic theory and practical method for color research.

本研究在提出颜色风格的科学概念的同时，在物理学、生理学、心理学和信息科学之间形成了新的结合点，提出了进行颜色风格研究的完整思路，为今后在这方面的研究提供了基础理论和技术方法。

As there were too much description between mathematic model and practice, many useful information was lost duding regression, the regression could not give satisfied results in color style research.

用多元回归的方法处理颜色风格的问题时，由于假设条件与实际情况的差异较大，加上在处理过程中不能充分利用所有的信息，因此颜色风格的预报函数不能准确地给出颜色风格特征。

We maintain that stagnation in Sino-U.S. relations is undesirable and that regression is even more undesirable. However, if something forces a regression in relations, we cannot but face reality squarely.

我们说中美关系停滞不好，倒退更不好，但是一旦发生某种事情迫使我们的关系倒退的话，我们也只能正视现实。

The error of the elongation is 2.3%, by the multi-dimension linear regression model, the relative error are from ? 5% to ? 15% respectively. Comparing the results, it can be found that the neural network overmatches the multi-dimension linear regression. So that, the model can be used in the production of the marine propeller aluminum bronze.

计算结果表明，三项输出的预测值与实测数据接近，抗拉强度和屈服强度的相对误差在±1％的范围以内，延伸率的最大绝对误差为2.3％，明显优于多元线性回归模型±5％—±15％的误差，能较好地满足工程应用的要求，对高强度船用螺旋桨铝青铜的生产具有一定的指导意义。

The outstanding characteristic of PLS is that it can make the multiple linear regression analysis, the principal components analysis and the canonical correlation analysis combined. In the same arithmetic, it can implement modeling, predigesting the data structure and analyzing of the correlation between two gropes of variables at the same time. It brings huge advantage to the multiple linear regression analysis.

PLS的一个突出特点是将多元线性回归分析、变量的主成分分析和变量间的典型相关分析有机地结合起来，在一个算法下，同时实现了回归建模、数据结构简化和两组变量间的相关分析，给多元数据分析带来极大的便利。

Regression analysis was used to associated factors,10 factors selected in the regression model included father lead exposure,did not wash their hands before the meal,the painted fitments in the rooms,usually play in the open air,the children's residence,sheet iron canned goods,peanut,bean,agaric and milk.

以血铅值为因变量，家庭装修、燃料、饮食等为自变量，经多元逐步回归分析(P=0.01)，有10个因素被选入方程，其中，父亲接触铅、儿童饭前不洗手、室内家具为油漆面、经常在户外玩、儿童所在居住地、吃铁皮包装的罐头制品、经常吃花生等7项因素与儿童血铅水平呈显著正相关

A case study shows that the stepwise regression model of daily runoff prediction based on wavelet decomposition is superior to auto-regression model, and is able to predict the daily runoff in 1~3 days in non-freeze-up period and 1~7 days in freeze-up period with accepted accuracy.

计算实例表明，本文提出的基于小波分解的逐步回归日径流预测模型的预测精度高于多元自回归模型，能对非凌汛期未来1~3天以及凌汛期1~7天的日均流量进行预测，能够为制定水电站未来的发电计划提供科学的依据。

Daughter-dam regression, daughter-dam regression wit hin sire, half-sib correlation and intro-unit half?sib correlation were used in the study to estimate genetic parameters for several traits of Albas type of In ner Mongolia cashmere goats, Traits included in this paper were cashmere yield,cashmere thickness,staple length,body eight,cashmere stretched length and cashmere fineness.

本研究应用女母回归法、公畜内女母回归法、半同胞相关法和单元内半同胞相关法对内蒙古阿尔巴斯白绒山羊的产绒量、绒厚、毛长、体重、绒伸直长度和细度等六个性状的遗传参数进行了估测。

Our study shows that Bax ,the protein of accelerating apoptosis, may participate in the proliferation and regression of hemangioma. 2 The expression of TGFβ1 in the involuting phase was higher than in the proliferative phase, the difference was statistically significant, p＜0.01. 3 This shows that Bax and TGFβ1 may be the important factors which cause the apoptosis of hemangioma and accelerate its regression as well.

1 Bax在血管瘤增生晚期开始表达，至退化期Bax的表达达到高峰，提示Bax这种促进细胞凋亡的蛋白参与血管瘤的增生与退化过程。2 TGFβ1在血管瘤退化期的表达高于增生期，差异有统计学意义，p＜0.01.3 提示Bax与TGFβ1可能是引起血管瘤凋亡，进而促进其退化的重要因素。
