Result obtained using the linear regression models.

E.g., at the top line, the final regression model predicted Class A FPKMs in LT-HSCs using TGAS I, resulting in the correlation coefficient . This model included 83.91 TFBSs consisting of 18.98 single TFBSs and 64.93 pairwise TFBSs.
*TFBS-Gene association scores; (I) MATCH score only, (II) including distribution of TFBSs, (III) including expression changes in TFs, (IV) same as (III) but only including TFBSs targeted by highly expressed TFs, and (V) including the TF–TF interactions in the log-linear model. (V) was modified to remove TFs: coded by undetectable transcripts (V-1), those that belonged to Class D (V-2), or by removing the 21 TFBSs in Figure 4B (V-3).
†Pearson's correlation coefficient; once the final regression model was found, R reflecting the model quality is calculated to measure the degree of correlation between the observed and predicted FPKMs.
