Response/RT/omission survival IRT reference model — fit_omission_survival

Fits a response model among reached/answered observations and cause-specific survival models for omission and not-reached processes. The function keeps the missingness mechanisms distinct by construction.

Usage

fit_omission_survival_irt(
  data,
  response = "response",
  response_time = "response_time",
  omission_time = NULL,
  reached = "reached",
  person = "participant_id",
  item = "item_id",
  gaze_exposure = NULL,
  first_fixation_latency = NULL,
  ...
)

Arguments

data: Input data frame or compatible tabular object.
response: Response variable or response-column name.
response_time: Response-time variable or column name.
omission_time: Time associated with an omitted response.
reached: Indicator that the item was reached.
person: Person or participant identifier column.
