| Abstract: | The linear regression analysis based on least square method is the project of solving dynamometer＇s equations of linear regression. The linear regression error （standard deviation） based on its analysis of the regression equation established is the smallest and optimal. It can provide data processing solution with high accuracy for highway engineering test. Its data processing can improve the efficiency combined with Excel, then get the visualized curve fitting interface. |
