R2 represents the explanation degree of different groups to sample differences, that is, the ratio of group variance to total variance. The larger R2 is, the higher the explanation degree of group differences is. Pr means p-value, less than 0.05 indicates that the reliability of this test is high. The value corresponding to the residual term is in parentheses.
