Fits a simple affine linking map on anchor observations and reports residual bias/RMSE by device. It complements, rather than replaces, IRT anchor linking.

Usage

cross_device_process_equating_audit(
  data,
  value,
  reference_value,
  device,
  anchor = NULL
)

Arguments

data

Input data frame or compatible tabular object.

value

Process-value column or values.

reference_value

Value supplied to `reference_value`; see Details for its model-specific role.

device

Device identifier or device facet.

anchor

Anchor or reference group used for linking.

Value

An object of class "eye_cross_device_equating_audit", "data.frame", stored as a data frame, containing cross-device process-scale equating audit and associated metadata needed to interpret the result.
