Audit structural and measurement support for M3

Performs a conservative pre-fit audit for the four-channel response, RT, fixation-count and pupil reference model. The audit checks design connectivity, channel coverage and variation, pupil nuisance availability, blink/interpolation burden, device/session representation and explicit M3 identification constraints. It is a support screen, not proof of global identifiability or construct validity.

Usage

audit_multimodal_m3_identifiability(
  x,
  pupil_scale = c("z", "raw"),
  min_persons = 20L,
  min_items = 5L,
  max_pupil_missing = 0.5,
  max_blink_rate = 0.3,
  max_interpolation_rate = 0.3
)

Arguments

x

M3-compatible data, simulation, fit, or measurement object.

pupil_scale

Pupil transformation used by the reference likelihood.

min_persons, min_items

Conservative design thresholds.

max_pupil_missing, max_blink_rate, max_interpolation_rate

Warning thresholds.

Value

An `eye_multimodal_m3_identifiability` object.
