  1. B(r xy ) - bias of the Pearson correlation coefficients estimated directly from the large expression matrix; B ( r ̄ xy ) - bias of the average of correlations between expression profiles within i = 1,19 groups; B(rxy ) - bias of the Pearson correlation coefficients estimated directly from the pooled residuals; B ( r ̄ xy ) - bias of the average of correlations between expression residuals within i = 1,19 groups.
