For common-average spectra at 20 to 100 Hz, inverse-frequency weights changed top contact sets in 12 of 19 SEEG records

Two fixed fit rules changed the top 10 percent contact set in 12 of 19 public SEEG records. We used 1,466 contacts from OpenNeuro ds003876 version 1.0.2. Each record supplied 120 seconds of common-average spectra. Fits used 20 to 100 Hz and excluded 57 to 63 Hz. We compared equal bin weights with 1/f weights. The equal patient mean slope change was -0.03220. Its 95 percent patient bootstrap interval was [-0.07103, +0.00345]. The exact sign flip test gave p = 0.12102 under patient independence and null sign symmetry. The primary test did not resolve a mean shift. Mean rank correlation was 0.97037. Mean top-set overlap was 0.86700. A saved residual audit accounts for each contact change by frequency. Exact power laws are invariant to these weights. The package preserves code, compact spectra, raw examples, source versions, hashes, results, and repeat instructions. The slopes do not isolate an aperiodic neural component. The study does not identify the better biological weight rule.
