查询词典 regression

The importance of testing for serial correlation in the error terms of a linear regression model has been recognized for many years. Some authors have investigated in detail this problem in the linear regression model.

多年来，人们已经认识到检验线性回归模型中误差项是否存在序列相关的重要性，(来源：ABc4C论文网www.abclunwen.com)并且对这个问题进行了广泛深入的研究。

In this thesis, we introduce three indexes that are used to evaluate the main business firstly. Theyre profit of main business, cashflow of main business and integrated index of main business. Then, we construct a series of regression models of assets structure with profit of main business and cashflow of main business, which signalize the current assets and the fixed assets help them; the long-term investments hinder them; the other assets help or hinder them uncertainly, and even have nothing to do with them sometimes. Finally, we construct the regression models of assets structure with integrated index of main business, and put forward a method to optimize the assets structure.

本文首先将主营业务指标分为主营业务利润、主营业务现金流量与主营业务综合指标；然后，通过构建资产结构与主营业务利润、资产结构与主营业务现金流量回归模型，发现流动资产、固定资产对主营业务利润和主营业务现金流量为正影响，长期投资对主营业务利润和主营业务现金流量为负影响，其他资产对主营业务利润和主营业务现金流量影响时有时无，时正时负；最后，在此研究基础上，构建资产结构与主营业务综合业绩指标回归模型，并提出优化资产结构的方法。

Results The values of sICAM-1,sVCAM-1 and tIgE in asthmatic patients were significantly higher than those in control (P＜0.01).There were 19 positive sIgE of artemisia pollen and 12 postive sIgE of dermatophagoides pteronyssinus in 23 patients.There was linear correlation between sICAM-1 and tIgE (R-square=0.502,standard partial regression coefficient=0.097,t=2.841,P=0.021 8) with stepwise regression analysis.

结果 血清sICAM-1、sVCAM-1、tIgE水平测定哮喘组均高于对照组(P＜0.01)；血清中以户尘螨和蒿草花粉的特异性IgE含量增高为主；经多元逐步回归分析提示血清总IgE含量与sICAM-1存在线性关系，其复相关平方为0.502，标准偏回归系数为0.097，t＝2.841，P＝
