Log mean posterior 8–13 Hz power had higher agreement across one month than rank Moran scores in 60 ds004148 adults with closed eyes and four second windows

This test used 60 adults from OpenNeuro ds004148 version 1.0.1. It compared posterior 8–13 Hz power with a rank Moran score of window order. The primary setting used closed eyes, an average reference, four second windows, 280 planned seconds, and visits about one month apart. Single measure absolute agreement ICC was 0.831 for log mean power and 0.233 for the temporal score. The paired difference was 0.598. Its 95% person bootstrap interval was 0.345 to 0.862. All nine planned checks had the same direction. Local order was present within records: mean temporal score was 0.263 and permutation p was 0.0001. Thus local order and repeat agreement gave different results in this test. The package supplies all 360 input spectra, source hashes, person scores, resampling records, code, an exact permutation moment proof for ties and gaps, and reproduction commands. Independent calculations checked all 1,257 record scores and 400,000 bootstrap ICCs. Four raw EEG replays reproduced every saved array exactly. The claim applies to this score, source processing, and cohort. It does not test all neural temporal measures.
