Spearman rank correlations for predictions obtained by perfect fits and minimization of L1- and L2-norms.

<p>The correlations are based on cross-validations, where the last column stands for an overall calculation based on 24 ranking lists. The minimization with respect to an L2-norm has the best performance, both for including only expression values and for including both expression values and rates. Following the principle of including as little as possible, we discard the rates.
