Description
Coverage bookkeeping for disjoint supplied direct, proxy-only and unknown reporting days.
Pediatric research records use chronological age, visit windows, measurement resolution, task observations, and caregiver reports. Missing observation differs from noncompletion, and a completeness share depends on its denominator. Arithmetic on supplied records is separate from a developmental or clinical assessment.
Coverage bookkeeping for disjoint supplied direct, proxy-only and unknown reporting days.
When to use this tool
Use Caregiver Report Window Base Flag when you need this age, observation, visit, measurement, or record-completeness calculation with supplied inputs.
How to use the tool and how it works
- Enter directDays, proxyOnlyDays, unknownDays, includeProxy. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read knownDays, denominatorDays, coverageDefined, coverage. Inspect coverageDefined before interpreting the associated values.
For nonnegative integer directDays, proxyOnlyDays, and unknownDays return knownDays=directDays plus proxyOnlyDays if includeProxy. DenominatorDays always includes all three categories; return coverage when positive, otherwise zero with coverageDefined=false.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| directDays | Direct Days | Required. Safe integer; minimum 0. |
| proxyOnlyDays | Proxy Only Days | Required. Safe integer; minimum 0. |
| unknownDays | Unknown Days | Required. Safe integer; minimum 0. |
| includeProxy | Include Proxy | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| knownDays | Known Days | Required. Safe integer. |
| denominatorDays | All direct, proxy-only, and unknown days, regardless of includeProxy. | Required. Safe integer. |
| coverageDefined | Coverage Defined | Required. Boolean. |
| coverage | Coverage | Required. Finite number. |

}Limitations and assumptions
- Categories must describe distinct days on one interval. Including proxy records changes support credit rather than the denominator or report accuracy; no independent caregiver verification is performed.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use verified dates, measurement protocols, and observation definitions for the intended research question. A clinical interpretation needs the relevant age-specific assessment and context beyond the arithmetic record check.
