基于多元线性回归的装饰工程快速估价模型

A Model of decoration engineering fast cost estimation based on multiple linear regression

针对目前装饰工程快速估价方法的不足,以及装饰工程造价组成的特点,建立一种基于多元线性回归的快速估价新模型。以住宅类建筑为例,建立其多元线性回归模型,结合SPSS软件对样本分析,结果表明,其线性回归模型显著,同时,内墙、外墙、楼地面和窗的回归系数也非常显著。通过计算回归值与实际值的误差,发现误差比较理想,该模型具有很好的实用价值。

According to the defeats of current methods and the cost composition characteristics of decoration engineering, this paper establishes a new model of fast cost estimation based on multiple linear regression, it takes residential constructions as an example, and uses spss software to analyze samples, results show that its multiple linear regression model is significant.at the same time, the regression coefficients of internal walls, exterior walls, floor and windows are also very significant, by calculating the error between regression value and actual value, it shows that this model has a good practical value.
