In search of objective components for sleep quality indexing in normal sleep.

Highlights: [•] We search for objective sleep quality measures. [•] We model sleep as a continuous process represented by a set of sleep microstates. [•] We correlate parameters of the sleep model with latent factors of daytime behavioral and life-quality measures. [•] We report a set of sleep parameters significantly correlating with daytime factors. [ABSTRACT FROM AUTHOR]
