Precision and recall
Revision as of 07:05, 17 July 2011 by Zeno Gantner (talk | contribs)
Precision or positive predictive value is a measure for exactness and recall or sensitivity is a measure of completeness. They range from 0 to 1 and the best possible value for both of them is 1.
- Precision = TruePositive / (TruePositive + FalsePositive)
- Recall = TruePositive / (TruePositive + FalseNegative)
