考虑到建成区面积受多个因素影响,利用MATLAB软件建立多元线性回归模型,并分析其回归方程的总体显著性,参数的显著性及拟合的优度,逐次剔除不显著的回归方程参数后建立多元线性回归方程,然后利用回归方程对建成区面积进行预测,并与实际测量结果对比。结果表明模型能够较准确地预测出建成区的面积值。
Taking into account the built-up area is affected by many factors, the use of MATLAB software to establish multiple linear regression model and analyze the overall significance of the regression equation, the significance of the parameters and the goodness of fit, after the elimination of the insignificant regression equation parameters Establish multiple linear regression equation, and then use the regression equation to predict the area of built-up area, and compare with the actual measurement results. The results show that the model can predict the area value of the built-up area more accurately.
