Retest Validation of Performance of the Whole-Brain SVM Classifier.

<p>For each participant in the re-testing group, the SVM from study 1 was used to distinguish the painful stimuli from the nonpainful stimuli. For each participant in the retesting group, and for their group average, this table displays the SVM's overall accuracy, and positive and negative predictive value (PV). Error is reported as 1 standard deviation. An asterisk indicates performance measures that are significantly greater than chance (<i>p<0.</i>05).
