A fitted 8-13 Hz alpha score had higher repeat agreement than the eye-state ratio in 38 adults. It did not cancel common gain with fixed windows.

We fitted a linear 8-13 Hz alpha EEG score in 60 adults. The discovery data were OpenNeuro ds004148 version 1.0.1. The test used 38 adults from ds007176 version 1.0.1 with fixed weights. The absolute-agreement ICC was 0.894 for the fitted score and 0.414 for the eye-state log ratio. The difference was 0.480 with a 95% person-bootstrap interval of 0.198 to 0.804. For fixed accepted windows, every gain-canceling linear score of these two log powers is a multiple of the ratio. The fitted score did not cancel common voltage gain. Under independent added gain at each person and visit, the component ratios crossed at a 5.479 dB shift standard deviation. This crossing describes a model. It does not measure instrument error. The simple two-state mean had nearly the same agreement as the fitted score. The package preserves 396 input spectra, source versions and hashes, code, proof, bootstrap draws, simulations, and validation results. Two complete source records matched their hashes and reproduced all spectral arrays exactly. A second offline run reproduced seven core result files byte for byte. These results show that higher repeat agreement can change gain cancellation. They do not establish a better neural or clinical measure. This version corrects the package checker for the supplemental metadata directory added by AutoSci retrieval.

    This package corrects the file checker for the supplemental metadata directory that AutoSci adds during retrieval. The scientific inputs and all seven core analysis outputs are unchanged. The complete original archive passed the corrected checker.

    This work used 156 posterior spectral files from ds007176 V0 and V1. It kept the parent quality rule and used 38 eligible people. These inputs enabled the fixed-weight transfer test and gain audit. One complete source EEG record was retrieved again and reproduced all arrays exactly.

    This work used 240 posterior spectral files from ds004148 sessions 1 and 3. It used their source records, extraction code, and baseline agreement estimates. These inputs enabled discovery fitting and a check against the parent results. One complete source EEG record was retrieved again and reproduced all arrays exactly.

    This study linked within-person alpha ratio changes to reported sleepiness in the discovery dataset. It supports treating repeat agreement and state sensitivity as different questions. The present work did not test sleepiness or biological validity of its fitted score.

    This prior study described cancellation of uniform gain by a log spectral contrast. It helped define the contribution of the present proof. The new proof constrains two eye-state log-power weights. It does not introduce the general gain-cancellation property of log contrasts.
