Digit-Symbol Coding Scaled Score Converter
Actual independently matched piecewise-linear calibration: Actual separately verified instrument age/cohort/edition raw-to-scaled-score conversion Digit-Symbol Coding Scaled Score Converter. Actual increasing verified RawScoreKnots, aligned verified ScaledScoreKnots, no extrapolation; example knots illustrative, not normative. Independent fit/branch/uncertainty and applicability external, not guaranteed physical outcome, clinical recommendation, design code or safety approval.
Description
Digit-symbol raw scores need an applicable instrument and normative stratum before conversion.
Digit-symbol raw scores need an applicable instrument and normative stratum before conversion.1
A supplied knot table provides conditional interpolation rather than an embedded publisher norm. The calculation and input requirements are explained below.
When to use Digit-Symbol Coding Scaled Score Converter
Read a conditional response from independently verified conversion or equipment-curve knots.
How to use Digit-Symbol Coding Scaled Score Converter and how it works
- Identify the curve edition, applicable stratum or equipment configuration, units and as-of date.
- Enter source metadata, aligned increasing x and response knots, and an in-range query; then run the tool.
- Read result.conditionalInterpolatedValue in the response unit together with the returned source metadata.
- Correct invalid knot order or an out-of-range query. Check that linear interpolation is appropriate for the supplied reference.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerVerifiedSource | Independently verified source identifier or edition; nonblank, at most 1024 characters. | string | Required; other constraints below |
| callerVerifiedContext | Applicability context, such as equipment, population, units, jurisdiction or protocol; nonblank, at most 1024 characters. | string | Required; other constraints below |
| callerVerifiedAsOfDate | Caller-declared as-of date; real YYYY-MM-DD calendar date in years 0001–9999. This is not automatically a retrieval or freshness date. | string | Required; other constraints below |
| verifiedRawScoreKnots | Verified Raw Score Knots. Use the units and matching context stated in the calculation below. | array of number | Required; other constraints below |
| verifiedScaledScoreKnots | Verified Scaled Score Knots. Use the units and matching context stated in the calculation below. | array of number | Required; other constraints below |
| actualQueryCoordinate | Finite query coordinate inside the supplied reference-knot range. | number | Required; finite; other constraints below |
Supply verified source, context and real Gregorian as-of date (YYYY-MM-DD, years 0001–9999), at least two strictly increasing finite reference x knots, aligned finite response knots and a finite in-range query. Find its bracketing interval and linearly interpolate the response; exact knots return their reference value, including both endpoints. Outside-range queries and duplicate x knots are errors. Return the conditional value with caller source, context and date. No normative or manufacturer table is installed, no extrapolation occurs and reference authority is not checked.
response=y_i+(y_(i+1)-y_i)*(query-x_i)/(x_(i+1)-x_i) Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.conditionalInterpolatedValue | Piecewise-linear response at the supplied in-range coordinate, in the response-knot unit. | number |
| result.source | Supplied source identifier, returned unchanged. | string |
| result.context | Supplied applicability context, returned unchanged. | string |
| result.asOfDate | Supplied valid as-of date, returned unchanged. | string |

}Limitations and assumptions
The tool performs forward linear interpolation only. It does not contain a normative or equipment table, estimate a new curve, extrapolate, propagate uncertainty or establish that interpolation is approved for the source.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
