Binary Count Table Youden Index Calculator
Binary Count Table Youden Index Calculator — Descriptive index of supplied labeled classification counts; no clinical recommendation or threshold optimization.
Descriptive index of supplied labeled classification counts; no clinical recommendation or threshold optimization. Calculations use finite-precision arithmetic.
Accepted inputs: TP value: 0 to 100,000 count; TN value: 0 to 100,000 count; FP value: 0 to 100,000 count; FN value: 0 to 100,000 count.
How the calculation works
Add true-positive and true-negative rates and subtract one.
Worked example
With tp value 40 count, tn value 50 count, fp value 5 count, fn value 10 count, result is 0.7090909091 number.
Assumptions and limits
