C.16.MR:4.2 - Follow the production of the indication

Trace the procedure from the subject through the interactions, transformations and sampling that produce the indication. For each consequential stage, identify the relation supplied by the physical principle, known operation, applicable calibration or response model.

Start with relations already available for the actual or proposed arrangement. A supplied conversion can be enough. When it is missing, derive it from the subject account or identify the empirical relation that must be learned. B.5.RC helps recover a construction from an unfamiliar description; B.5.FM helps formulate the first model.

Retain an intermediate value when another relation uses it or when it exposes a consequential interaction. In the voltmeter example, current connects the source equation to the meter indication. Eliminate that current only after the relations use the same current and conditions.

For a statistical procedure, describe how response probabilities depend on the sought property and relevant conditions. The expected response and one realized sample are separate inputs to inference. Learning or transporting the response model requires the subject’s estimation and applicability work.
