Figure 8From: Comprehensive analysis of correlation coefficients estimated from pooling heterogeneous microarray dataComparison betweenB( r xy ∗ ) andB( r ̄ xy ∗ ).B( r xy ∗ ) is the bias of the Pearson correlation coefficients estimated directly from the pooled residuals;B( r ̄ xy ∗ ) is the bias of the average of correlations between expression residuals within i = 1,19 groups.Back to article page
