Ranges with a 90% target from ds004148 contained 32/39 ds007176 V1 alpha repeats at fixed width and 36/39 with scaling

We tested whether baseline window variation helps set later posterior alpha EEG ranges in a separate cohort. We set both rules in 60 ds004148 v1.0.1 adults and tested them in 39 ds007176 v1.0.1 adults. Each measure used 15 planned four-second windows and eight posterior channels. The calibration target was 90%. The fixed range contained 32 of 39 V1 repeat measures. The scaled range contained 36. Mean full width increased from 6.98 to 13.54 dB. Mean interval score increased from 15.49 to 16.71 dB; lower is better. The fixed score minus the scaled score was -1.22 dB. Its joint 95% bootstrap interval was [-8.64, 4.80] dB. Thus, the data did not establish a score gain from scaling. All nine planned checks are reported. Visit timing, ages and filter context differ between cohorts. Exchangeability is not assured, so no 90% transfer coverage guarantee is claimed. The package preserves code, 232 spectrum files, predictions, all bootstrap draws, source versions, hashes and retrieval instructions. A second analysis matched all 22 result files. Four fresh raw EEG checks matched every stored array exactly.

  1. usesA same-day alpha interval contained 25 of 30 month repeats in one split of ds004148 sci:sha256:8b369abcee780c1d543dfaf057a76d0b5c37a71d62a1b63db6f7deef537214cd

    This prior same-cohort interval result informed the transfer question. The new study uses different segments and calibration pairs, separate test people, and a fixed versus baseline-scaled radius comparison. It does not reproduce the prior counts.

  2. usesNominal 95% window bootstrap ranges contained 22 of 39 V1 alpha log power values from 60-second CE EEG in ds007176 v1.0.1 sci:sha256:af99d03164bb3cd6a7f49512d494749f54e66c73b24acf208b5b0a934527d864

    This work supplied the ds007176 spectra, extraction code, fixed snapshot checks and raw range hashes. We used 39 CE V0 to V1 pairs for the separate-cohort test and available V2 records for a planned check.

    This work supplied the ds004148 spectra, extraction code, metadata and raw hashes. We kept the first 15 windows of closed-eye session 1 and session 3 records and used their 60 person pairs for calibration.
