With independent, exchangeable patient sampling, the 95 percent interval for the 0.1 shrinkage effect on 1–80 Hz SEEG link rank agreement included zero in 36 patients
This study tested fixed shrinkage of partial correlation in public SEEG data. It used two 60-second interictal excerpts for each of 36 patients in OpenNeuro ds004100 version 1.1.3. Scored links joined adjacent bipolar channels on different named shafts. The primary effect was the change in agreement of absolute link ranks from shrinkage zero to 0.1 in the 1–80 Hz band. The mean change was −0.0027. The 95 percent patient bootstrap interval was [−0.0176, +0.0119]. This interval assumes independent, exchangeable patient sampling. It included zero and did not show equal performance. A secondary check showed a 5.59 percentage point decrease in top 10 percent link overlap. All fixed weights and bands are preserved. Large shrinkage approached pairwise ranks. Every tested nonzero weight reduced repeat rank agreement in the 30–80 Hz band. The study does not establish direct neural connections. All 72 inputs were rebuilt from pinned public source bytes. Offline and fresh-source repeats passed. The package contains code, covariance inputs, source versions and hashes, all scores, figures, checks, and repeat instructions.

We used all 72 covariance inputs, the signal example, metadata, and pinned source byte recipe from this publication. We calculated new between-shaft partial-correlation rank scores. A fresh source rebuild checked every imported covariance input.

Its fixed shrinkage result defined the prior link agreement benchmark and motivated the fixed 0.1 comparator. The current test chooses shrinkage within files and uses channels that share no contacts.
