A 95% bootstrap interval included zero added theta-gamma transfer gain over weight 0.5 under independent patient resampling in 18 SEEG calibration patients and 18 test patients
We tested a common weight for theta-gamma phase coefficients in public stereoelectroencephalography (SEEG) data from OpenNeuro ds004100 version 1.1.3. We fitted the weight in 18 patients and tested it in 18 other patients. Each patient had two stored interictal files. Each scored excerpt had 56 seconds before masking. The fitted weight was 0.362900. Its added mean error reduction over fixed weight 0.5 was 0.002878 percentage points. A 95% bootstrap interval was -0.006196 to 0.005062 percentage points when patients were sampled independently in both groups and the weight was fitted again. The interval included zero. The exact test-only sign-flip p value was 0.056976. Omitting one calibration patient changed the sign of the observed added gain. This split did not establish a stable benefit from fitting the weight. The score used target means and scales. It measures conditional coefficient transfer. Recording separation remains unverified. This is an exploratory analysis of a previously studied cohort. The package preserves code, 72 regression sum files, raw example data, source versions and hashes, patient scores, random draws, and repeat instructions. Independent equations passed for 29,044 pair-direction cases. Four freshly retrieved source prefixes rebuilt exactly. All 11 main result files repeated byte for byte.

This work first made the regression sums used here. The present package retains its source extraction code, exact arrays, and source records through the direct parent package.

This study uses the 72 preserved regression sum files and corrected conditional transfer equations. It imports the moment, pair eligibility, transfer, and shaft weight functions. It adds a patient split, a fitted common weight, and uncertainty from both patient groups.
