Precision and recall In statistical analysis of binary classification, the F-score or F-measure is a measure of a test's accuracy. This is the F beta score: F β = (1 + β 2) ⋅ p r e c i s i o n ⋅ r e c a l l (β 2 ⋅ p r e c i s i o n) + r e c a l l The Wikipedia article states that F β "measures the effectiveness of retrieval with respect to a user who attaches β times as much importance to recall as precision". I did not get the idea. The F-beta score is the weighted harmonic mean of precision and recall, reaching its optimal value at 1 and its worst value at 0.
