Probability distributions of the electroencephalogram envelope of preterm infants

Probability distributions of the electroencephalogram envelope of preterm infants

Highlights • Probabilities of preterm EEG envelopes were distributed lognormally at ages of 38 weeks or less. • The probabilities were better described by gamma distribution at the end of the neonatal period. • The distribution transitioned from lognormal to gamma as its skewness decreased. • The sc...

Zusammenfassung:Highlights • Probabilities of preterm EEG envelopes were distributed lognormally at ages of 38 weeks or less. • The probabilities were better described by gamma distribution at the end of the neonatal period. • The distribution transitioned from lognormal to gamma as its skewness decreased. • The scale parameter, skewness, and mode were indicators of how the preterm EEG activity matures.
