Worked example
Illinois row 70 is a DL record with no result value. The condition is Not Detected; the inline limit is 0.1 ug/L of type Minimum Reporting Level; the fraction is Total and the method is 8141.
| Step | Result |
|---|---|
| Documented semantics | DL documents non-detection; Minimum Reporting Level is a reporting-limit role. |
| Policy | reporting_total admits reporting limits as censoring thresholds. |
| Canonical record | status eligible, censored TRUE, observation 0.1 ug/L. |
| Group | Atrazine/Total/8141. |
| Audit | Input SHA-256, policy, source row and counts are recorded. |
Bound caveat. The inline reporting limit is at or above the unavailable method detection limit for this record. Censoring at the reporting limit is a looser, upward-biased threshold relative to the MDL; the magnitude is unquantified.
