统计回归模型的研究 摘 要 统计回归模型是用一个或多个其他变数来预测一个变量。Abstract Statistical regression models are used to predict one variable from one or more other variables. Regression models provide the scientist with a powerful tool, allowing predictions about past, present, or future events to be made with information about past or present events. At the same time, the statistical regression model is a broad and practical significance application in reality. This paper major research the application of statistical regression model in real life, the purpose is apply what they have learned. The article is divided into three parts: the first part is the concept of statistical regression model and basic knowledge; the second part is the examples of statistical regression model in real life, for example, in the telecommunications industry, chemical industry, agriculture, etc; the third part is a summary of the article. Articles related to some knowledge in undergraduate study, such as least squares solution and the t test, F test, error analysis, residuals analysis, interval estimation. This is a review and consolidation to the previously learned knowledge. Hope through research to be able to really achieve the desired effect that theoretical knowledge apply to real life, better service for the community.
