In eyeprocess: Harmonize Eye-Tracking, Pupillometry, Biometrics, and Psychometric Process Data

Declare an eyeprocess IRT model specification

Description

This specification records a psychometric model contract. Estimation is delegated to explicit engines where required; the specification itself does not fit a model.

Usage

eyeprocess_irt_model_spec(
  family = c("rasch", "2pl", "3pl", "4pl", "grm", "gpcm", "nominal", "multidimensional",
    "testlet", "latent_regression", "cdm", "joint_rt"),
  dimensions = 1L,
  identification = c("theta_standard", "item_sum_zero", "anchor"),
  engine = c("native_math", "mirt", "TAM", "GDINA", "LNIRT", "eRm", "custom"),
  process_channels = character(),
  status = c("reference", "experimental", "gated"),
  notes = NULL
)

Arguments

family	IRT response family or model family.
dimensions	Value supplied for the dimensions argument.
identification	Identification specification or identification audit.
engine	Requested estimation or analysis engine.
process_channels	Declared process-measure channels.
status	Evidence, model, or governance status.
notes	Value supplied for the notes argument.

Value

An object of class "eyeprocess_irt_model_spec", stored as a named list, with components "family", "dimensions", "identification", "engine", "process_channels", "status", "notes". It contains declare an eyeprocess IRT model specification and associated metadata or diagnostics needed to interpret the result.
