The 95 percent interval for two-second beta map prediction gain included zero in 17 SEEG patients under independent, exchangeable sampling

We tested whether strong earlier signed beta maps predict later estimates with less squared error than zero. The test used 30 public SEEG records from 17 patients in epilepsy evaluation. Each map used two seconds. Each test patient's scale was fitted in the other patients. Mean gain was 0.50 percent, with a 95 percent patient bootstrap interval of -1.20 to 2.69 percent. The interval includes zero under independent, exchangeable patient sampling. Copying the early estimates at full scale increased error in all 17 patients. All seven fixed check intervals included zero. This work reuses a studied cohort and is not an independent replication. All 355 source hashes passed, and fresh raw signals rebuilt all 30 input records exactly. The package includes code, epochs, edge maps, results, checks, figures, and retrieval instructions.

    Its magnitude-based top-edge retention result in the same cohort informed this signed-map prediction question. This work uses a different endpoint and a scale fitted with each test patient excluded.

    This work uses its paired epochs, source manifest, extraction audit, and unchanged extraction code. A fresh public download rebuilt all inputs exactly.

    Its signed-map agreement and fixed half-scale error result informed the distinction between agreement and prediction error. This work tests fitted scales in another public SEEG cohort.
