Mean later log RT squared error reduction was -0.332 percent with added 20 Hz burst features in eight SEEG patients

We tested whether 20 Hz burst features before a cue add value to later response time prediction. RT means response time. We used 1,988 offline selected trials from eight patients in public OpenNeuro ds004473 version 1.0.2. SEEG means stereoelectroencephalography. The ridge reference used task context and mean 20 Hz power. The added model also used burst presence and last peak position. All thresholds and fits used earlier training data. The test contained 500 later trials. The mean patient reduction in squared log RT error was -0.332 percent. Each patient had equal weight. The 95 percent patient bootstrap interval was [-1.417, 0.642] percent. It includes zero. Four gains were zero because the fixed procedure removed neural terms. Two patients had no valid inner tuning split. Task order and clinical contact coverage limit the test. This result does not show that beta activity lacks RT information. The package contains 10,160,100 envelope bins, trial predictions, fitted thresholds and coefficients, code, raw fixtures, provenance, and repeat instructions. Fresh public requests reproduced all arrays exactly. Two complete analysis repeats gave identical numerical files.
