The month alpha contrast error gain interval included zero for offline split EEG in 59 ds004148 adults at 120 seconds per eye state

We tested two first-day EEG rules at the same planned time in OpenNeuro ds004148 version 1.0.1. The split used 60 seconds per eye state from each of two sessions. The latest rule used 120 seconds from session 2. The target was posterior 8 to 13 Hz eye-state log power contrast one month later. The fixed test retained 59 adults. Latest mean squared error was 15.28 dB squared. Split error was 16.75. The gain was -1.47, with a 95 percent whole-person bootstrap interval of -4.21 to 1.11. The interval included zero. It did not establish benefit or equal error. All eight raw forecast check intervals also included zero. A separate offset check used month data from other people. Its gain was 1.85, with an unadjusted interval of 0.16 to 3.60. It needs independent validation. An exact fixed-pool calculation separates squared pool-mean error and window sampling variance. The archive contains all 360 spectra, source identities, code, decisions, draws, figures, and repeat commands. Six fresh raw records reproduced every array exactly. A second run matched all 33 analysis outputs. The short windows inherit full-record filters. The result does not validate a new short acquisition. The work extends earlier equal-duration tests in the same cohort.

    Its two-session forecast question for alpha frequency informed our choice of a later observed EEG target. The present fixed test uses alpha eye-state power contrast and equal planned time. It is not an independent cohort confirmation.

    Its month contrast calibration study informed the fixed offset check and identity exclusion in refitted bootstrap draws. We use separate mean offsets for the latest and split rules, rather than its linear model comparison.

    This archive supplied the 360 unchanged window spectra, the extraction code, raw content identities, headers, and source metadata. We verified all 1,815 files in the copied dependency record. Six fresh raw records reproduced all saved arrays exactly.

    A final search found this prior equal-duration study after the new results were calculated. It includes a latest-session control at 280 seconds. It defines the prior scope. The present report adds the fixed 120-second result with log after mean power, the offset allocation check, and exact fixed-pool risks.
