[Abstract]:Three new univariate linear regression methods with coordinate independence are proposed, which are the principal component linear regression method. The sparse data linear regression method based on polar / minimum axisymmetric envelope domain and the single variable linear regression method based on moment of inertia are proved to be superior to the existing methods by simulation experiments. Two new binary linear regression methods with coordinate independence are proposed: principal component binary linear regression and binary linear regression based on polar / minimal axisymmetric envelope set. A fast algorithm is designed for the envelope set method. The advantages of each method are proved by simulation experiments. In this paper, a new multiple multivariate linear regression method with coordinate independence is proposed, which is based on reduced dimension hyperplane. This paper puts forward a W- index to evaluate the financial risk of M & A financing of coal enterprises, and uses three methods to make regression analysis to determine the parameters of W- index. The univariate correlation and multivariate mixed correlation between the main business income and the book value of fixed assets and non-fixed assets in the statements of coal listed companies are studied. The correlation function between variables is given by binary linear regression method.
