mvpa2.clfs.transerror.corr_error(predicted, target)

Computes the correlation between the target and the predicted values. Resultant value is the 1 - correlation coefficient, so minimization leads to the best value (at 0).

In case of NaN correlation (no variance in predictors or targets) result output error is 1.0.
