Description
Return forecast-vintage timing relative to its origin.
Business timing and cohort summaries depend on event origins, bucket boundaries and the treatment of incomplete records. A time difference or bucket label is a supplied record convention rather than proof of customer behavior, completed service or future retention.
Return forecast-vintage timing relative to its origin.
When to use this tool
Use Forecast Vintage Origin Gap when checking the stated business timing or cohort convention.
How to use the tool and how it works
- Enter vintageAt, forecastOrigin. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read gap. Use the output convention below.
Return forecast-vintage timing relative to its origin. gap = vintageAt-forecastOrigin in the common supplied clock basis.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| vintageAt | Vintage At | Required. Finite number. |
| forecastOrigin | Forecast Origin | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| gap | Signed difference under the stated comparison convention, with matching units. | Required. Finite number. |

}Limitations and assumptions
- Signed offsets do not establish actual data availability, forecasting leakage or valid retrospective evaluation.
- 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 complete event records and a defined cohort/period policy; evaluate commercial performance and uncertainty with appropriate complete analyses.
