regression also needs to examine multiple collinearity problems, but here, because of the small correlation between the variables, it is possible to preliminarily judge that there is no multi-collinearity problem, and of course we can use VIF (variance expansion factor) to test multiple collinearity problems after modeling. If there are multiple collinearity, it is possible that there are two variables highly correlated, requiring dimensionality reduction or culling processing.Figure 4. Correla

. We've all heard the old saying: "If you don't measure what you're doing, you can't improve it."
