Description
Return unclassified remainder and both fractions of the full period.
Research schedules and activity records use numeric intervals, pauses, and overlap conventions. The same endpoints can produce different summaries depending on whether simultaneous activities are counted once or separately.
Return unclassified remainder and both fractions of the full period.
When to use this tool
Use Geriatric Diary Missing Hour Share when you need a time-budget or interval calculation in geriatric research records.
How to use the tool and how it works
- Enter periodHours, recordedHours, explicitlyMissingHours. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read unclassifiedHours, recordedFraction, missingFraction. Use the output convention below.
Require positive periodHours and nonnegative recordedHours and explicitlyMissingHours whose sum fits it. Return unclassified remainder and both fractions of the full period.1
| Input field | Meaning and units | Accepted input |

| periodHours | Period Hours | Required. Finite number; strictly above 0. |
| recordedHours | Recorded Hours | Required. Finite number; minimum 0. |
| explicitlyMissingHours | Explicitly Missing Hours | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| unclassifiedHours | Unclassified Hours | Required. Finite number. |
| recordedFraction | Recorded Fraction | Required. Finite number. |
| missingFraction | Missing Fraction | Required. Finite number. |

}Limitations and assumptions
- Unclassified time is distinct from explicitly missing time; record completeness, actual observation, functional status, and clinical interpretation are not inferred.
- 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
Reconcile the full schedule and source timing convention before aggregation. Use an appropriate observational or clinical assessment for questions that duration arithmetic cannot answer.
