Description
Propagate supplied diary recall uncertainty, without symptom or diagnostic scoring.
Research questionnaires and interview records distinguish answered, declined, omitted, unpresented, and inapplicable items. Timing and support annotations also affect their denominators. A completeness measure or scale transformation describes those records without establishing an instrument score or a mental-health assessment.
Propagate supplied diary recall uncertainty, without symptom or diagnostic scoring.
When to use this tool
Use Diary Recall Start Precision when you need the particular completeness, timing, polarity, or bookkeeping term for supplied research and interview records.
How to use the tool and how it works
- Enter endDay, recalledStartLower, recalledStartUpper. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read durationLower, durationUpper. Use the output convention below.
Return durationLower=endDay-recalledStartUpper and durationUpper=endDay-recalledStartLower. Require ordered recalled-start bounds ending no later than endDay.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| endDay | End Day | Required. Finite number. |
| recalledStartLower | Recalled Start Lower | Required. Finite number. |
| recalledStartUpper | Recalled Start Upper | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| durationLower | Duration Lower | Required. Finite number. |
| durationUpper | Duration Upper | Required. Finite number. |

}Limitations and assumptions
- These are deterministic timing bounds under supplied recall uncertainty, not diagnostic episode durations, confidence limits, symptom thresholds, or a validated assessment.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use the relevant validated instrument and its documented missing-response and scoring procedures when the task requires an assessment. Verify research annotations and timing before combining record terms.
