Sleep metrics for single in-bed intervals
Each epoch within an in bed interval is scored as either Wake or Sleep. Contiguous
epochs of the same type are grouped to create Wake and Sleep periods. Metrics for
each in bed interval are calculated based on the Wake and Sleep periods as shown
in Figure 1.

Sleep Onset Latency
– The length of time between the first attempt to get to
sleep and sleep onset.
SleepOnsetLatency = Sum of all epochs scored as wake from the start of
the in bed period up to the start of the first epoch scored as Sleep.
