#> [1] "eye_negative_control_evidence_plan"Stress dimensions include gaze missingness, pupil dropout, calibration offsets, sampling jitter, AOI-label noise, device shifts, and trial imbalance. Reliability evidence includes split-half, ICC, temporal stability, and Bland-Altman-style agreement. Negative controls include permutations, temporal shifts, placebo windows, and intentionally known leakage.
Thresholds and perturbations are study-specific reporting conventions. Reliability is not validity, and negative-control/leakage findings are not misconduct labels.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
