Cross-device process-scale equating audit — cross_device_process_equating

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.
