Description
Compare feature publication lag with a supplied allowance.
Model validation depends on when information became available and how records or entities enter splits. A timestamp inequality or group overlap count can identify one local issue without proving absence of every form of leakage.
Compare feature publication lag with a supplied allowance.
When to use this tool
Use Feature Availability Lag Gap when checking an explicit feature-time or split-membership condition.
How to use the tool and how it works
- Enter eventAt, availableAt, allowedLag. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read lag, gap. Use the output convention below.
Compare feature publication lag with a supplied allowance. Require allowedLag >= 0; lag = availableAt-eventAt, gap = allowedLag-lag.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| eventAt | Event At | Required. Finite number. |
| availableAt | Available At | Required. Finite number. |
| allowedLag | Allowed Lag | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| lag | Lag | Required. Finite number. |
| gap | Gap | Required. Finite number. |

}Limitations and assumptions
- Negative lags are retained; no provenance, actual release time or causal feature eligibility is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a complete data-provenance and validation-design review, including label horizons, entity dependence and preprocessing fit scope.
