摘要
本文详细的阐述了线性回归方法和用MATLAB对回归模型的简化。线性回归分析是工程中经常采用的一种用来估计数学模型参数的方法。并且它为机器的磨损状态的变化提供了比较准确的信息。因此,线性回归分析进一步促进了铁谱诊断系统的研究、设计与发展。
In this paper. Linear regression method and simplification of regression model with MATLAB were described in detail Linear regression analysis is usually used to estimate the parameters of a mathematical model in engineering. Moreover it supplies the more accurate information for variety of mechanical wearing state. Hence linear regression analysis further facilitaes the development.design and research of ferrograpic diagnosis system.
