Selection by jackknife precision gave 55.23 percent mean beta phase slope sign agreement across adjacent minutes in 19 SEEG patients

This study tested whether selection by jackknife precision increased beta phase slope index sign agreement across adjacent minutes. It used 19 public SEEG patients from OpenNeuro ds003876 version 1.0.2. Each rule selected the top 10 percent of contact pairs from different name groups. Precision used six jackknife blocks of ten seconds. Mean sign agreement was 55.23 percent for precision selection and 55.86 percent for raw magnitude selection. The mean change was -0.64 percentage points. The descriptive 95 percent patient bootstrap interval was -2.31 to +0.76 points. The exact two-sided patient sign-flip test gave p = 0.4981. This test assumes independent patients and symmetric null contrasts. Ten patients improved and nine did not. The rules shared 49.6 percent of selected pairs. No mean gain was detected in these clips. This reused cohort does not establish equal performance or causal accuracy. Fresh source retrieval rebuilt all 19 inputs exactly. A second analysis matched all 649 saved arrays. The package preserves code, inputs, all pair results, source identities, retrieval recipes, checks, and reproduction instructions.
