Piotroski F-score is a number between 0 and 9 which is used to assess strength of company's financial position. The score is used by financial investors in order to find the best value stocks (nine being the best). The score is named after Stanford accounting professor Joseph Piotroski. [1]
Precision and recall. In statistical analysis of binary classification and information retrieval systems, the F-score or F-measure is a measure of predictive performance. It is calculated from the precision and recall of the test, where the precision is the number of true positive results divided by the number of all samples predicted to be positive, including those not identified correctly ...
Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing series administered by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body. [1] The "formula" in the name alludes to a series of rules set by the FIA to which all participants and vehicles are required to conform.

To calculate the recall for a given class, we divide the number of true positives by the prevalence of this class (number of times that the class occurs in the data sample). The class-wise precision and recall values can then be combined into an overall multi-class evaluation score, e.g., using the macro F1 metric. [21]
An F-score is a combination of the precision and the recall, providing a single score. There is a one-parameter family of statistics, with parameter β, which determines the relative weights of precision and recall. The traditional or balanced F-score is the harmonic mean of precision and recall:
P 4 metric [1] [2] (also known as FS or Symmetric F [3]) enables performance evaluation of the binary classifier.It is calculated from precision, recall, specificity and NPV (negative predictive value).
The disadvantages of the use of financial result as a Key performance indicator. Operating components may be included in the financial result (e.g.: the income from financing activities).
