The patient test detected no group versus random removal difference in 19 SEEG records under an independent symmetric null. Common average sets used 120 seconds of 80 to 150 Hz power.

We tested contact group removal from a common average reference in 19 public SEEG records. Each record supplied 120 seconds. The feature was mean 80 to less than 150 Hz power. We compared top 10 percent contact sets with the same retained contacts in each pair. Each group had 1000 random controls with the same removal count. Mean set disagreement was 0.639 percent for groups and 0.375 percent for random removals. The mean difference was 0.264 percentage points. Its 95 percent patient bootstrap interval was -0.021 to 0.636 points. The exact two-sided sign flip p value was 0.1386. The test assumes independent patients and a symmetric patient null. It does not establish equivalence. Secondary effects varied across bands and time halves. The package supplies a power equation, band matrices, source pins, random draws, and independent checks.
