1归模型预测技术中最小二乘法的改进摘要:回归模型预测技术中釆用最小二乘法计算回归模型参数理论上存在一定的缺陷，是模型在进行中长期时产生较大误差。通过对最小二乘法进行改进,在一定程度上弥补这种缺陷，提高了回归模型的适用性和稳健型。Abstract:Inregressionmodelprediction,weusuallycalculatetheregressionmodelparametersusingtheleastsquaresmethod.Therearesomeflawsinthetheory;sothatthemodelproduceslargeerrorswhenmakinglong-termforecasts.Thepapermakesupforthisdeficiencytothecertaindegreebyimprovingthemethodofleastsquaresandimprovetheapplicabilityandrobustnessoftheregressionmodelatthesametime.关键词：回归模型预测；最小二乘法；误差分析。
