The algorithm has been\nvalidated against event markers using data from the\nMulti-Ethnic Study of Atherosclerosis (MESA) Sleep study, and\nits methodological details are described in Chen and Sun (2024)\n. The package provides functions to\nestimate sleep metrics (e.g., sleep and wake onset times) and\ncircadian rhythm metrics (e.g., mesor, phasor, interdaily\nstability, intradaily variability), as well as tools for\nscreening actigraphy quality, fitting cosinor models, and\nperforming parametric change point detection. The workflow can\nalso be used to segment long actigraphy sequences into\nregularized structures for physical activity research.", "License": "GPL (>= 3)", "Encoding": "UTF-8", "LazyData": "true",
