After the regression analysis of the main physical and chemical indexes, we can get the relationship between them. The main physical and chemical indexes of red grape and red wine were analyzed by regression analysis. The linear correlation indexes were total phenol and total phenol, Anthocyanin and Anthocyanin, resveratrol and resveratrol, Tannin and Tannin, etc. , an example of regression analysis between Anthocyanins and Anthocyanins is shown in figure 2. The horizontal and vertical axes shown in Fig. 2 are the observed values and the expected values of the cumulative probability respectively. It can be concluded that the anthocyanins in red grapes are linearly correlated with the anthocyanins in the physical and chemical indexes of wine.
