multimodal_irt_spec: Consolidated multimodal IRT specification

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

Consolidated multimodal IRT specification

Description

This is a thin multimodal adapter over the established 'irt_model_spec()' / 'eye_irt_model_spec' architecture. It composes existing 'eye_irt_channel' objects and does not define a parallel channel or model-specification ecosystem.

Usage

multimodal_irt_spec(
  response = NULL,
  rt = NULL,
  gaze = NULL,
  pupil = NULL,
  model = c("M0", "M1", "M2", "M3"),
  backend = c("cmdstanr", "existing"),
  identification = list(),
  priors = list()
)

Arguments

response, rt, gaze, pupil	Existing 'eye_irt_channel' objects or NULL.
model	Development model identifier.
backend	Requested backend.
identification	Named identification settings retained as explicit multimodal metadata.
priors	Named prior settings retained as explicit multimodal metadata.

Value

An 'eye_multimodal_irt_spec' convenience subclass of the established 'eye_irt_model_spec'.
