Differential Correlation Mining

This method was developed to identify sets of genes that are more inter-correlated under one condition than under another; genes that are correlated among patients with a certain disease, but uncorrelated among those without the disease. The DCM method relies on statistical testing principles to iteratively search until a significantly differential set is discovered.
