多元线性回归
Abstract
Many phenomena are often not simply associated with a number of factors but with
varieties. At this point we need to use two or more factors as independent variables to explain changes in the dependent variable. This is also known as multiple regression. When more than one independent variable and the dependent variable are linear relationship, the regression analysis is carried out by diversity regression.
The main research work of this thesis is divided into four parts. In the first chapter, the thesis proceed from the basic content and object of study and elaborate main content simply. In the second chapter, multiple linear regression model is analyzed detail. In the third chapter, the thesis introduces status quo of china. And at last, gross industrial production is analyzed by multiple linear regression model in this article.
Over all, this article use the specific data of the output of major industrial products and industrial output in nationwide provinces in 2007, and select the output of plastics, cement, steel, plate glass, crude steel, wire rod and raw coal as study object to establish multiple linear regression model, and then make the model parameter estimation. Based on this,we make some explanations to the model. All of these are of momentous current significance and far-reaching historical significance to the forecast of industrial production.
