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`.
