Label
Standard deviation of sleep maintenance efficiency in main sleep on weekdays from actigraphy
Description
Sleep maintenance efficiency is the ratio between sleep duration (i.e. total sleep time, tst) and sleep period in main sleep. Sleep duration is the interval between sleep onset time and sleep offset time while asleep, while sleep period is the interval between sleep onset time and sleep offset time.
This variable is similar to variable sawa34; however, sawa34 is derived from Actiware variable sawa24 before data optimization.
