(2016) and van Someren et al. (1999) . Additionally, it also computes L5\n(i.e. the 5 hours with lowest average actigraphy amplitude) and\nM10 (the 10 hours with highest average amplitude) as well as\nthe respective start times. The flex versions will also compute\nthe L-value for a user-defined number of minutes. IS describes\nthe strength of coupling of a rhythm to supposedly stable\nzeitgebers. It varies between 0 (Gaussian Noise) and 1 for\nperfect IS. IV describes the fragmentation of a rhythm, i.e.\nthe frequency and extent of transitions between rest and\nactivity. It is near 0 for a perfect sine wave, about 2 for\nGaussian noise and may be even higher when a definite ultradian\nperiod of about 2 hrs is present. RA is the relative amplitude\nof a rhythm. Note that to obtain reliable results, actigraphy\ndata should cover a reasonable number of days.", "License": "GPL-3", "Language": "en-GB", "LazyData": "true", "Roxygen": "list(markdown = TRUE)",
