From: The ‘un-shrunk’ partial correlation in Gaussian graphical models
Comparison of partial correlations from Eschericha coli microarray data. Volcano plot of the partial correlations pcorr and the –log10(p-values). [18] The figure is segmented into four regions using a threshold of |pcorr|= 0.1 and p-values = 0.05 (dashed lines). In grey: The ‘shrunk’ estimates. In black: The new ‘un-shrunk’ estimates
