Description
Count expected records and the valid expected subset, returning their ratio or zero with defined false for no expected records.
Cross-source records often use different labels, time spans, and support conventions. Exact equality and overlap checks describe the supplied metadata; they do not prove that sources measure the same social or geographic concept.
Count expected records and the valid expected subset, returning their ratio or zero with defined false for no expected records.
When to use this tool
Use Country Series Valid Period Share when you need a literal source comparison or coverage diagnostic.
How to use the tool and how it works
- Enter valid, expected. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read validExpected, expectedCount, share, defined. Inspect defined before interpreting the associated values.
Require aligned valid and expected flags. Count expected records and the valid expected subset, returning their ratio or zero with defined false for no expected records.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| valid | Whether this specific check passes; not necessarily a full object-validity verdict. | Required. Array of boolean; maximum items 256. |
| expected | Expected | Required. Array of boolean; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| validExpected | Valid Expected | Required. Safe integer. |
| expectedCount | Expected Count | Required. Safe integer. |
| share | Dimensionless share on the numerator and denominator basis stated above. | Required. Finite number. |
| defined | Whether the stated denominator or normalization exists; inspect before interpreting a zero placeholder. | Required. Boolean. |

}Limitations and assumptions
- Rows are unweighted and flags are supplied; no country identity, time-series continuity, indicator definition, or source validity is independently checked.
- 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.
Alternative or Complementary methods
Inspect the original source definitions and collection methods. Harmonize conceptual scope and timing before treating matching labels or overlapping records as comparable evidence.
