  1. N = number of samples per class. (Precision is also known as positive predictive value; recall is also known as sensitivity; F1-score is the harmonic mean of precision and recall). The p-value is computed using the two-tailed Mann–Whitney U test to reject the null hypothesis that each valve is indistinguishable from the others in a 1 vs all framework.
