- W2374068045 abstract "The method of Least Square is often used to estimate parameters for industry data modeling.When the data meet certain conditions,the unbiased estimation is obtained.However,there usually are measurement errors in the industry data,based on which Least Square estimation is often biased.So the estimated values can not accurately describe the structural relationship of the independent variables and the dependent variable.The dual variables model is deeply analyzed,and by reasonable assumption of measurement errors,an analytic relationship between true value and measurement errors,biased estimated value is established.The simulation result shows the effectiveness of the proposed method." @default.
