| Abstract: | ??Based on statistical tests and prediction precision analysis of the linear regression model,which was formulated in"Some thought on study of mathematical model of contemporary book publishing in China"(Li Hua),this paper indicates that the criticism to the model,which was given in"Suggestions on the mathematical model of contemporpary book publishing in Chin"(Lan Ling),is incorrect,then reformulates the model to solve the autocorrelation problem and cuts dowm the prediction error. |
