How this works. All analysis runs locally in JavaScript — no data is
sent anywhere, no server is involved, and you can read the source of this page. It is the browser
version of the test kit, limited to the checks that need only one column.

What each check means
| Check | Interpretation |
|---|---|
| Threshold | How many values sit exactly on your threshold. A comparison written as >= against a computed threshold silently discards these. |
| Quantisation | Chi-square of the last digit against uniformity. Large values mean a rounding convention is present. |
| Estimator spread | Two standard ways of estimating the same exponent. A spread above about 1.05 means the choice of estimator matters as much as the data. |
| Digit audit | Which digit is most over-represented, and by how much. |
A defect found once can be checked for everywhere in minutes. That is the only reason to
automate an inspection.
