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 article will utilize multiple linear return the measurement analysis tool to carry on the analysis in entire asian area several inferior regions drawing up with superior , the currency cooperation first has launched in the association of southeast asian nations inferior region , realized the currency unification in the small scope , this process will advanced also in entire area currency ’ s cooperation mechanism , thus enable the east asian currency cooperation pattern to have gradualness at the same time 文章运用多元线性回归的计量分析工具对整个东亚地区的几个次区域的拟和优度进行了分析,货币合作将首先在东盟次区域展开,在小范围内实现货币的统一,这一过程将与区内的整个货币合作机制同时推进,从而使东亚货币合作模式同时具有阶段性和层次性的特征。
Thirdly , i will analyse the chinese stock market . and all of these , i talk about the function of chinese stock market in detail . finally , i will empirically analyse the problem by using multiple regression analysis and draw a conclusion that the relation between the chinese stock market and the economic growth is positively correlated 在本文的最后一部分，借鉴国外先进的理论模型，采用逐步回归法，利用1998年? 2003年中国股票市场与宏观经济季度数据，对股票市场与经济增长的关系进行了回归分析，得出了多元线性回归模型，并对其结果进行了相关的分析，分析的结论是中国股票市场与经济增长具有显著的正相关性，也就是股票市场对经济增长确实有促进作用。
Combined with data from current securities market in china , chapter 3 utilizes statistic and multi - analysis , comparatively researches the differences of the corporate governance structure and management performance between the absolute - controlled and relatively - controlled listed state - owned enterprises , comparatively analyses the structure and the operating quality of board of directors between the absolutely - controlled and relatively - controlled listed state - owned enterprises , gives imperical research on the influence of shareholding alteration upon management performance of the corporations 论文的研究侧重在结合我国当前的证券市场数据,运用统计和多元线性回归方法,比较研究绝对控股和相对控股的国有上市公司法人治理结构在公司经营绩效上的差异性;比较分析绝对控股和相对控股的国有上市公司董事会的构成及运行质量;实证研究股权结构对公司经营绩效的影响。
To take full advantage of corporate data collected in territory management and give full play to their value , the author also adopted some management accounting tools in this article to probe into these data more deeply . for example , the author adopted the multivariable linear regression method to forecast sales and the principal component analysis method to assess territory market , etc 为了对区域管理获得的公司数据资源进行充分合理的利用，使之发挥最大价值为公司所用，在本文中作者还运用了一些管理统计工具对这些数据进行了更深入的挖掘，如用多元线性回归方法进行销售预测、用主成分分析方法对区域市场进行评估等。
Abstract : on the basis of the experimental data of microstructure and strength for gray cast iron with high carbon equivalent , the adapted fuzzy neural network model of relationship between microstructure and strength for predicting the strength of gray cast iron has been developed by using adaptive neural - fuzzy inference method . comparing with the models based on multiple statistic analysis , fuzzy regression or generalized regression neural network , it shows better learning precision and generalization 文摘:以高碳当量灰铸铁组织-强度实验数据为基础，用自适应模糊推理方法，建立了灰铸铁强度自适应模糊神经网络预测模型，与多元线性回归、模糊回归和广义回归神经网络模型相比，该模型学习精度高且具有较好的泛化性。
Consequently , it is very necessary to make a general analysis about these influencing factors . at the first , this paper makes an analysis on the whole sample and draw a conclusion as follows : the stock - keeping ratio of management supervisors in ( msr ) chinese public companies is low , evenly distributed and vary acutely . secondly , this paper generalizes seven predictors from corporation ' s performance , ability of value development , property structure , character of human resource , and asset to explain the dependent variable msr by a multiply linearity equation 其次，本文从业绩、价值成长能力、股权结构、管理者人力资本特征以及公司规模五个方面出发，抽象出对管理层持股具有影响作用的七个解释变量，构造了以管理层持股比例为被解释变量的多元线性回归方程，利用spss11 . 0软件，采用全部纳入法和逐步回归分析法进行回归拟合，并采用标准参数检验( t检验和f检验)来确定其相关显著性。
The main human driving forces are population growth , industrialization and urbanization , development of the tertiary industry , the mechanism of economic management , social behavior , etc . ( 3 ) quantitative analytical methods such as principal components " analysis , multi - linear regression model , and stepwise regression model etc can be used for analyzing the direction and speed of luc within certain period , and can connect luc with human driving forces very well 影响土地利用变化的主要人类驱动力因素主要有人口增长、工业化和城镇化、第三产业的发展、经济管理机制、社会行为等。 ( 3 )主成分分析法、多元线性回归模型、逐步回归法等定量分析方法可以较好地用来分析在一定时段内土地利用变化的方向和变化速度，能很好地将人类驱动力因素与土地利用变化有机地联系起重庆市不同经济区土地利用变化的人类驱动力研究来。
Through the excel program , and combining the inside and outside environment of the excavation and stress field and displace field , the data of stress and displacement of points are analyzed in variable depth and load grade and terminal state . the spss software has been applied to the statistics of geometry parameter of failure surface , and the failure surface criterion is created by the linearity regression from d ( the longest horizontal distance between the failure surface and the side face of the slope ) , ho ( the depth 此外，应用spss软件对试验破坏滑弧的几何参数进行统计分析，并对滑弧的最大水平深入距离d及d处至坑底的高度h _ 0结合各水理指标进行多元线性回归，建立滑面的判据，并对此判据进行修正，且用实际工程对其进行评价，通过反算已知滑面的c 、值，表明边界条件对破坏形式有极大的干扰作用，所直接看到的破坏类型土体不是发生整体滑移破坏，而是剥落式的溃屈破坏。
The part using the data of population agglomeration degree and labor amount of three industries , according to the econometrics principle , constructs the multi - variable linear regression model for each of the 31 provinces , municipalities and autonomous regions " so as to find out the realistic relationship between city and industrial development all through the country 文章根据全国以及全国31个省、直辖市和自治区的城市人口聚集度与三次产业从业人员的数据关系运用计量经济学原理一一构建了多元线性回归模型，以揭示我国各地区的城市发展和产业结构的实际关系，并得出一系列结论。
