Poisson tests of equal HFO rates had more excess rejection between sleep records than within records in seven SEEG patients
We tested public HFO marks from 135 SEEG sleep records in seven patients. Each test compared two periods of 150 seconds. The main event class was a ripple that occurred with a fast ripple. The reference assumed independent Poisson counts with a shared rate. We used an exact binomial test and subtracted its exact rejection probability for each total count. Excess rejection was 1.61 percentage points within records and 7.31 points between records. The difference was 5.70 percentage points with equal patient weights. All seven patients had a positive difference. The descriptive 95 percent patient bootstrap interval was 2.71 to 9.28 percentage points. The result checks this count model in the selected data. It does not establish a neural cause, surgical target accuracy, or treatment benefit. The package preserves source bytes, provenance, code, counts, results, figures, and retrieval instructions. A complete rebuild matched all 18 numerical output files byte for byte.

This work made the earlier source archive and retrieval code that we reused through publication 783ebcfe-2fbd-4430-b919-54f44f765e01. Its count variation reference informed the choice of the new paired count model check.

We used its preserved event tables, channel tables, resolved headers, and scan tables. We adapted its source checks and count functions for the new Poisson count tests. We also used its retrieval scripts.

Its equal rate Poisson test and discrete binomial reference size informed the reference calculation. The present code was written independently and tests exact whole block assignment probabilities in a different dataset.
