多元统计分析是统计学的一个重要分支，是应用数理统计学来研究多变量问题的理论和方法，是一元统计学的推广和发展．文章主要就多元统计分析中的线性回归模型进行深入的研究和分析，首先对多元线性回归模型的建立和最小二乘解的算法进行了推理，然后分析了其在销售中的应用．%Multivariate statistical analysis is an important branch of statistics, it is the application of mathematical statistics to the study of the theory and method of variable problems, and it is the promotion and development of？ unary statistics. In this paper, we have a further research and analysis of the linear regression model of multivariate statistical analysis.
