Fit a standard 3PL and audit lower-asymptote alignment with process evidence

Source: R/068-bayesian-3pl-process-diagnostics-0-8.R
fit_gaze_anchored_3pl_audit.Rd

Fits a conventional 3PL response model with `mirt`, then aligns the fitted lower-asymptote parameter with item-level gaze/pupil/RT summaries. The alignment is descriptive and diagnostic. It must not be interpreted as a confirmatory detector of guessing, rapid responding, disengagement, or any other latent behavior without independent validation.

Usage

fit_gaze_anchored_3pl_audit(
  response_matrix,
  process_data = NULL,
  item = "item_id",
  process_features = c("ttff_ms", "dwell_ms", "pupil_bc", "pupil_peak", "rt_ms",
    "accuracy"),
  model = 1,
  SE = FALSE
)

Arguments

response_matrix

Person x item dichotomous response matrix.

process_data

Optional trial/person-item process table.

item

Item identifier in `process_data`.

process_features

Candidate numeric process features.

model

mirt model specification.

SE

Request standard errors from `mirt`.

Value

An `eye_gaze_anchored_3pl_audit` object.
