Pre-pulse energy had a mean partial rank association of 0.081 with late waveform deviation in seven selected SEEG patients after fixed source correction and pulse number adjustment

The study tested pre-pulse energy against late waveform deviation in public OpenNeuro ds004696, version 1.0.1. Seven selected epilepsy patients supplied 80 groups and 1,516 contact-group records. Each group used ten selected good pulses. The primary measure was a partial rank association after linear adjustment for selected pulse number. Contact means were averaged within groups, groups within patients, and patients with equal weight. The mean was 0.081071. All seven patient means were positive. The conditional 95 percent patient bootstrap interval was 0.034760 to 0.144171. The exact two-sided patient sign reversal test gave p = 0.015625. This test assumes independent patients and symmetric patient associations under a zero null. The source correction remained fixed and used other pulse information. Local contact subtraction gave a mean of 0.084724. Linear time detrending gave two negative patient means. The result describes a small voltage association. It does not establish a causal neural process or future response prediction. The package preserves inputs, code, tables, checks, source versions, hashes, and reproduction commands.
