A robust signature obtained with RS-PL from the neuroblastoma data set (π = 0.68).

The second column shows the mean values of selection probabilities of exon features. Multiple selection of exons from a single gene suggests differential expression, while the others indicate possible mutations. The relevance of features without references were extracted from the GeneCards (http://www.genecards.org). The corresponding ranks of chosen features (probesets) in Dev and Cor methods are shown in the last two columns (‘-’ if not chosen).A robust signature obtained with RS-PL from the neuroblastoma data set (π = 0.68).
