FormulaPrecision = tp/(tp+fp); Recall = tp/(tp+fn); Specificity = tn/(tn+fp); F1 = 2*tp/(2*tp+fp+fn); Mcc = (tp*tn-fp*fn)/sqrt((tp+fp)*(tp+fn)*(tn+fp)*(tn+fn))

How to use this tool

  1. Enter the labeled inputs using consistent units.
  2. Check the stated assumptions and calculate.
  3. Review each output and compare another input scenario.

Try this example

{
  "tp": 40,
  "fp": 10,
  "fn": 5,
  "tn": 45
}

Accuracy and scope

Strictly positive cells prevent undefined metrics. Evaluate on held-out data; threshold selection is not optimized here. Finite floating-point arithmetic; results can lose precision near singular or extreme inputs.
