Online statistics calculator to calculate measurement of a test’s accuracy for type I and type II errors by using F score (also F1 measure) formula.
What is F Score?
In statistics, the F score (also F1 score or F measure) is a measure of a test's accuracy. It considers both the precision p and the recall r of the test to compute the score: p is the number of correct positive results divided by the number of all positive results, and r is the number of correct positive results divided by the number of positive results that should have been returned.
Formula:
where,
β = Shape parameter
TP = Number of true Positives
FN = Number of false negatives
FP = Number of false positive
Fβ = F1 score
β = Shape parameter
TP = Number of true Positives
FN = Number of false negatives
FP = Number of false positive
Fβ = F1 score
