poisson exceedance probability calculator online

Use poisson exceedance probability calculator online for mean, threshold. Probability strictly above an integer threshold; threshold at most 170. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.

How to use it

Enter mean. Set threshold. Select Calculate and check the labeled output. Copy or download the JSON result.

Calculation method

exceedance_probability = poissonTail(mean,threshold) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply poisson exceedance probability calculator to the case below, keeping the displayed units and assumptions. Probability strictly above an integer threshold; threshold at most 170.

Choose the right tool

Choose number theory for exact integer relationships, distribution tools for a declared random model, and geometry tools for coordinates. A density is not a probability and a statistical model does not establish a real-world outcome.

Limitations and common mistakes

  • Probability strictly above an integer threshold; threshold at most 170. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
