Generation of the scale-free first-order similarity network. (a) Pearson’s correlation coefficient Cor and linear regression R² between lg (K) and lg (pK) when setting different first-order similarity thresholds. K refers to the degree value, while pK refers to the frequency of the degree value. (b) The distribution of lg (K) and lg (pK) and the Pearson correlation coefficient. (c) R² of the linear regression equations for lg (K) and lg (pK), and the relationship between the predicted and true values. The threshold value was set to 0.25.
