The basic concepts, principles and operation methods of regression analysis are introduced, and their application to ironmaking production is analyzed. Based on the contents of each part, specific examples of production of ironmaking are given. All lectures are divided into five parts: outline, one-element linear regression, one-element non-linear regression, polynomial regression and multiple linear regression. Each regression lists the basic calculation formulas, test methods, and dispersion analysis. The emphasis of the story is on practicality. The mathematical derivation is simple and easy to understand, the method of calculation is detailed, and it is easy for readers to master.
