Posterior 8–13 Hz EEG log ratio agreement was higher for alternating windows than for consecutive halves in 60 adults using 140 planned seconds per eye state
We tested EEG alpha ratio agreement in 60 adults from OpenNeuro ds004148 version 1.0.1. Each estimate used 140 planned seconds per eye state. The primary ICC difference between consecutive halves and one-month pairs was 0.082. Its 95% bootstrap interval was -0.341 to 0.486. This result did not establish higher within-session agreement. Alternating windows gave within-session ICC 0.955; consecutive halves gave 0.547. An added exploratory comparison gave a difference of 0.408, with interval 0.128 to 0.748. The package preserves all 360 source-derived spectrum files, source checksums, code, results, and reproduction steps. This is a new analysis of existing data. It does not add an independent sample.

This study used all 360 archived window-spectrum files, pinned source metadata, and the extraction code. It tested agreement for two split methods and repeated visits. It reproduced three full-record month ICC values as a check. It used the same participants. It did not add an independent sample.

Its EEG result motivated a comparison of alternating samples and consecutive halves at equal sample counts. This study tests movie fMRI with a different connectivity measure. It reuses no input data or code from that publication.
