binary kullback leibler divergence calculator online

Use binary kullback leibler divergence online for p p, q p. Both probabilities strictly between zero and one; direction matters. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.

How to use it

Enter p p. Set q p. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
p pMain input. Zero or positive values. Maximum 1.0.4
q pOption. Zero or positive values. Maximum 1.0.6

Calculation method

divergence_bits = entropytwo(p_p,q_p) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply binary kullback leibler divergence to the case below, keeping the displayed units and assumptions. Both probabilities strictly between zero and one; direction matters.

Calculated result for these inputs:

Output:

{
  "divergence_bits": 0.1169925001442311
}

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

  • Both probabilities strictly between zero and one; direction matters. 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.
