Formula and methodology
Formula: For sorted values xi, Gini=Σ(2i−n−1)xi/(nΣxi).
The list, sorting convention, and population-style coefficient are made visible so the distribution summary can be reproduced.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Nonnegative values, comma-separated
Worked example
| Input | Value |
|---|---|
| Nonnegative values, comma-separated | 10,20,30,40 |
Gini coefficient =0.25.
Assumptions and limits
- Values are finite, nonnegative, and represent one comparable population or sample frame.
- At least two observations are supplied and their sum is positive.
- Weights, sampling design, top-coding, taxes, household size, and causal explanations are not modeled.
