Under patient independence and null sign symmetry, a test detected no mean 20–100 Hz slope change between averaging orders in 19 SEEG patients
This study compared two orders of power averaging and logarithm in 19 public SEEG patients from OpenNeuro ds003876 version 1.0.2. It used eight 15-second windows and 1,466 contacts. The fixed straight-line fits used 20–100 Hz, with 57–63 Hz removed. Averaging power before the logarithm changed the mean slope by −0.00660. The 95% patient bootstrap interval was −0.02784 to 0.01096. The exact sign flip test gave p = 0.58218. The test assumes patient independence and null sign symmetry. This is not an equivalence result. The top 10% contact set changed in 10 of 19 patients. The mean rank correlation was 0.98642. An exact algebraic diagnostic accounts for every slope change. The diagnostic follows standard least squares algebra and Jensen's inequality. It does not identify a neural cause. This study reuses an earlier patient sample and does not select a preferred biological measurement. Independent calculation checked all contacts. Original source checks covered three patients at three sample rates. The package preserves code, spectra, raw examples, source hashes, results, figures, and instructions for a full source repeat.

We used its 19 archived SEEG spectrum files, original signal examples, source metadata, range receipts, and retrieval code. We changed the frequency weights in the line fit. We did not repeat its averaging-order hypothesis.
