摘要
经典多元线性回归分析不能实时跟踪响应变量的动态变化,而且在样本中会因少量病态数据的出现而影响拟合效果,基于以上原因文章提出将灰色系统[2]理论中的GM(1,1)模型与经典多元线性回归分析相结合产生灰多元线性回归分析模型,并将其应用到陕西省的房地产业中,以预测房地产的价格,从而为房地产商提供决策信息。
Classical multiple linear regression analysis can not be tracked the response variables＇ dynamic change in time and the fitting results would be impacted for a small amount of sick data. For these reasons this paper will combine the gray system theory of GM （ 1,1 ） with the classical model of multiple linear regression analysis to produce the model of gray multiple linear regression. And apply it to the real estate industry in Shaanxi Province to forecasting the real estate prices for real estate business to make decisions.
