  1. P-Value is the significant index of the calculated regression coefficient, which is significant if it is less than 0.05; Durbin Watson is used to test the independence between samples, and the closer its value to 2, the stronger the independence between samples, and the higher the reliability of the calculation results. VIF is the Variance Inflation Factor, the closer its value is to 1, the lighter the degree of multicollinearity between independent variables, and on the contrary, the heavier.
