  1. Note: The values in the top triangle represent the correlations between frequency vectors, while values in the low triangle are the correlations between exchangeability matrices. The greater the absolute value of the Pearson correlation coefficient, the higher the correlation. *: p < 0.05, significant correlation; **: p < 0.01, extremely significant correlation
