Strike Days Per Thousand Workers Calculator
Observed strike person-days per1000worker-person-years. Actual aligned same-period numerator/denominator strata, pooled by exposure not unweighted mean. Nonnegative counts/exposures and positive total denominator; overlapping strata must be independently resolved. No cohort representativeness, causation or eligibility inferred.
Description
Strike person-days measure the sum of affected worker-days.
Strike person-days measure the sum of affected worker-days.1
Normalizing by matched worker-person-years creates a rate that depends on observation scope rather than merely event counts.
When to use Strike Days Per Thousand Workers Calculator
Use this tool to obtain observedPooledRate, observedNumeratorTotal, observedDenominatorTotal from the supplied records using the stated calculation. Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
How to use Strike Days Per Thousand Workers Calculator and understand its results
- Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
- Enter observedStrikePersonDays, matchedWorkerPersonYears, using the field meanings and rules below, then run the tool.
- Read result.observedPooledRate, result.observedNumeratorTotal, result.observedDenominatorTotal. Use the units and sign conventions below, and review any unknown records separately.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedStrikePersonDays | Observed strike person days | list of number | Required |
| matchedWorkerPersonYears | Matched worker person years | list of number | Required |
Supply nonempty aligned finite nonnegative numerator and denominator lists for the same strata. Their denominator total must be positive. Pool the totals before dividing and scale by 1000. Return both totals alongside the pooled rate. The implementation does not require integer counts or enforce numerator≤denominator; it neither averages stratum rates equally nor converts units. The supplied definitions determine whether the result is a percentage, a per-population rate or another ratio.
pooledRate=1000×Σnumerators/Σdenominators; numeratorTotal=Σnumerators; denominatorTotal=Σdenominators Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or qualified reference | object |
| result.observedPooledRate | Scaled pooled numerator/denominator rate; its units and scaling follow the declared formula. | number |
| result.observedNumeratorTotal | Sum of the supplied nonnegative numerator records. | number |
| result.observedDenominatorTotal | Sum of the matched nonnegative denominator records; required to be positive. | number |

}Limitations and assumptions
Population definitions, survey design, calibration and observation coverage are independently established. A result describes the supplied record or conditional model without demonstrating causation, validating an instrument or supplying representative population evidence.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. Extremely large composite outputs are rejected.
