process_preflight_spec: Specify a biometric process pre-flight gate

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

Specify a biometric process pre-flight gate

Description

Defines transparent, review-oriented thresholds for incoming gaze/pupil data. The specification is a data-quality governance object, not a behavioral or clinical classifier.

Usage

process_preflight_spec(
  min_gaze_validity = 0.8,
  min_pupil_validity = 0.7,
  max_gaze_missingness = 0.25,
  max_pupil_missingness = 0.3,
  min_valid_trial_fraction = 0.7,
  trial_gaze_validity_threshold = 0.75,
  min_rt_ms = 200,
  max_rt_ms = 10000,
  sampling_rate_tolerance = 0.2,
  blink_quantile = 0.95,
  caution_flags = 1L,
  review_flags = 2L
)

Arguments

min_gaze_validity	Minimum mean gaze-validity proportion.
min_pupil_validity	Minimum mean pupil-validity proportion.
max_gaze_missingness	Maximum mean gaze-missingness proportion.
max_pupil_missingness	Maximum mean pupil-missingness proportion.
min_valid_trial_fraction	Minimum fraction of trials meeting the trial-level gaze-validity threshold.
trial_gaze_validity_threshold	Gaze-validity threshold used to count an acceptable trial.
min_rt_ms, max_rt_ms	Plausible mean response-time bounds in milliseconds.
sampling_rate_tolerance	Fractional deviation from the cohort median sampling rate that triggers review.
blink_quantile	Cohort quantile used for an extreme blink-cluster flag.
caution_flags	Number of flags yielding 'use_with_caution'.
review_flags	Number of flags yielding 'review_or_exclude_from_biometric_models'.

Value

An 'eye_process_preflight_spec' object.
