Mean seizure onset label AUC was 0.795 without 80 to 150 Hz time concentration and 0.804 with it in fixed logistic model tests of 34 SEEG patient holdouts with two 60 s clips each

We tested whether 80 to 150 Hz power concentration added seizure onset label prediction beyond mean power. The sample had 34 SEEG patients, two 60-second clips each, and 3,325 selected bipolar pairs from OpenNeuro ds004100 version 1.1.3. Every test patient was absent from training. Fixed logistic models used high mean power, beta mean power, and contact number. Adding high band concentration changed mean patient AUC from 0.79485 to 0.80419. The mean change was 0.00934, with a descriptive 95 percent interval of -0.00156 to 0.02150. Adding concentration to a baseline that also had beta concentration gave a mean change of 0.00118. The intervals resample saved patient results and omit model refitting uncertainty. The package includes all 68 input files, features, models, predictions, source identities, code, and commands. New signal downloads reproduced all input power values. Independent fits gave the same primary AUCs. An offline run reproduced all 31 analysis files byte for byte. The result applies to the fixed models and selected clinical labels. It does not establish a population gain or clinical use.
