Animal Exposure Score Matrix

Resolve an animal-contact exposure score from a caller-defined matrix; not an infection prediction.

Description

A score matrix can encode how contact categories and evidence categories map to exposure scores.

A score matrix can encode how contact categories and evidence categories map to exposure scores. The matrix is a caller-defined policy, not an internally selected risk model.

The tool returns exposureScore (exposure score); aboveThreshold (above threshold). Input measurements and model parameters are supplied by the caller; the tool computes the stated summary rather than acquiring those measurements.

When to use Animal Exposure Score Matrix

Use Animal Exposure Score Matrix when you already have contactIntensityScore, animalInfectionEvidenceScore, scoreMatrix, flagThreshold and want exposureScore, aboveThreshold. This is useful for checking a supplied calculation, documenting a measurement convention, or comparing observations prepared on the same basis.

How to use Animal Exposure Score Matrix and understand its results

Enter contactIntensityScore, animalInfectionEvidenceScore, scoreMatrix, flagThreshold using the field table below. Match the units, ordering and data boundaries described in the calculation.
Run the tool after checking the stated bounds and matching paired observations or categories. A malformed request gives a tool error rather than a usable measurement.
Read exposureScore, aboveThreshold. Use the calculation and interpretation below to distinguish amounts, ratios, signs and decision flags where applicable.
Review the supplied parameters and assumptions before using the result in a report or comparing it with another observation.

Input field	Meaning	Value type and bounds	Requirement
contactIntensityScore	Contact intensity score	integer	Required
animalInfectionEvidenceScore	Animal infection evidence score	integer	Required
scoreMatrix	Score matrix	list of list of number	Required
flagThreshold	Flag threshold	number	Required

Require a nonempty rectangular matrix and nonnegative integer indexes within its dimensions. Retrieve the row-column entry and apply the supplied threshold.

score = matrix[contactIndex][evidenceIndex]; flagged = score ≥ threshold

The symbols refer to the supplied quantities or generated values described above; unit conversions and comparison boundaries follow the stated implementation.

Limitations and assumptions

Indexes are zero-based. Scores and thresholds are not clinically validated by the calculator, and evidence is not collected or interpreted automatically.

Numerical inputs must be finite. The tool checks its declared input shape and calculation constraints; those checks do not verify the quality, calibration or representativeness of the supplied observations.
