Chance after di new signal
Na you supply the probability inputs; this tool no derive them from diagnosis or real-world population.

You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
P(A|B)=P(B|A)P(A)/(P(B|A)P(A)+P(B|¬A)P(¬A))
Update prior chance with signal rates for when di condition true or false.
Example wey show the calculation
- Chance before di new signal (%)
- 1
- Signal rate when di condition true (%)
- 99
- Signal rate when di condition false (%)
- 5
- Chance after di new signal
- 16.6666666667 %
- Overall chance of di signal
- 5.94 %
Where e fit work and limits
Na you supply the probability inputs; this tool no derive them from diagnosis or real-world population.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
