## Figure 2.
Comparison of correlation and mutual information based co-expression measures in 8
empirical data sets. Absolute value of bicor versus A^{MI,UniversalVersion2 }for all probe pairs in each data set. The Spearman correlation and corresponding p-value
between the two measures are shown at the top. The two measures show different levels
of monotonic relationships in data sets. The red curve predicts A^{MI,UniversalVersion2 }from bicor based on Eq. 18. The blue circle highlights the probe pair with the highest
A^{MI,UniversalVersion2 }z-score among those with insignificant bicor z-scores (less than 1.9 ); the red circle highlights the probe pair with the highest bicor z-score among
those with insignificant A^{MI,UniversalVersion2 }z-scores (less than 1.9 ).
